bttv_init_card2() sets btv->has_audio to a *default* value from the tvcards
array and then may update it by reading a card specific eeprom or gpio
detection.
After bttv_init_card2(), bttv_init_tuner() gets called, and it should clearly
use the updated, dynamic has_radio value from btv->has_radio, rather then
the const value in the tvcards array.
This fixes the radio not working on my Hauppauge WinTV.

Before this patch the owner field of the /dev/radio# device fops was set to
the snd-tea575x-tuner module itself. Meaning that the module which was using
it could be rmmod-ed while the device is open, and then BAD things happen.
I know, as I found out the hard way :)
Note that there is no need to also somehow increase the refcount of the
snd-tea575x-tuner module itself, since any drivers using it will have
symbolic references to it.

There are many different Medion X10 remotes that need slightly different
keymaps. We may not yet have all the needed keymaps, in which case a
wrong keymap may be used. This happened with Medion X10 OR2x remotes
before the keymap for them was added, causing the ati_remote driver to
select the Medion Digitainer keymap instead. Unfortunately, the Medion
Digitainer keymap doesn't have the standard X10 up/down scancodes
assigned to KEY_UP and KEY_DOWN keycodes, making wrongly assigned
remotes mostly unusable.
Add the regular KEY_UP and KEY_DOWN scancodes to the Medion X10
Digitainer keymap, making any Medion remote mostly usable even when
wrongly used with that keymap (standard buttons, such as
up/down/left/right, 0-9, play/stop/pause, have the same scancode in all
the X10 remotes).

The Logitech pan/tilt reset UVC control contains two V4L2 button
controls to reset pan and tilt. As the UVC control is not marked as
auto-update, the button bits are set but never reset. A pan reset that
follows a tilt reset would thus reset both pan and tilt.
Fix this by not caching the control value of write-only controls. All
standard UVC controls are either readable or auto-update, so this will
not cause any regression and will not result in extra USB requests.

There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.
Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.

In mx2_camera_try_fmt(), when applying i.MX25 restrictions to frame sizes,
the height is checked to be <= 0xffff. But later an integer multiplication
height * 4 * 0x3ffff is performed, which will overflow even for bounded
height values. This patch switches to using 64-bit multiplication and

MPIS based STBs running 3.x kernels and the Enigma2 OS are not able to tune
DVB-T channels with the PCTV 290e using the current cxd2820r driver.
DVB-T2 channels instead work properly.
This patch fixes the problem by changing the condition to break out from the
wait lock loop in the "search" function of the cxd2820r demodulator from
FE_HAS_SIGNAL to FE_HAS_LOCK.
As a consequence, the "search" function of the demodulator driver now returns
DVBFE_ALGO_SEARCH_SUCCESS only if the frequency lock is successfully acquired.
This behavior seems consistent with other demodulator drivers (e.g. stv090x,
hd29l2, stv0900, stb0899, mb86a16).
This patch has been successfully tested with DVB-T and DVB-T2 signals,
on both PC and the mipsel STB running Enigma2.
No apparent side effect has been observed on PC applications like Kaffeine.
DVB-C is not available in my country so it's not tested.

If the V4L2_EVENT_SUB_FL_SEND_INITIAL was set, then the application expects
to receive an initial event of the initial value of the control.
However, commit c53c254933 that added the new
v4l2_subscribed_event_ops introduced a regression: while the code still queued
that initial event the __v4l2_event_queue_fh() function was modified to ignore
such requests if sev->elems was 0 (meaning that the event subscription wasn't
finished yet).
And sev->elems was only set to a non-zero value after the add operation
returned.
This patch fixes this by passing the elems value to the add function. Then the
add function can set it before queuing the initial event.

The radio-si470x-usb driver supported both autosuspend and it stopped the
radio the moment the last user of the radio device closed it. However, that
was very confusing since if you play the audio from the device (e.g. through
arecord -D ... | aplay) then no sound would play unless you had the radio
device open at the same time, even though there is no need to do anything
with that node.
On the other hand, the actual suspend/resume functions didn't do anything,
which would fail if you *did* have the radio node open at that time.
So:
- remove autosuspend (bad idea in general for USB radio devices)
- move the start/stop out of the open/release functions into the resume/suspend
functions.

Since we don't know how to lower the brightness setting when not

to set the JPEG quality, but the correct bits are bits 1-2. Bit 0 selects
between truncation or rounding in the quantization phase of the compression,
since rounding generally gives better results it should thus always be 1.

different settings.
Last this patch removes the different reg 8 defaults depending on the sensor

There are two bugs here: first the calls to stop0 (in gspca_suspend) and
gspca_init_transfer (in gspca_resume) need to be called with the usb_lock held.
That's true for the other places they are called and it is what subdrivers
expect. Quite a few will unlock the usb_lock in stop0 while waiting for a
worker thread to finish, and if usb_lock isn't held then that can cause a
kernel oops.
The other problem is that a worker thread needs to detect that it has to
halt due to a suspend. Otherwise it will just go on looping. So add tests
against gspca_dev->frozen in the worker threads that need it.
Hdg, 2 minor changes:
1) The finepix device is ok with stopping reading a frame halfway through,
so add frozen checks in all places where we also check if we're still
streaming
2) Use gspca_dev->dev instead of gspca_dev->present to check for disconnect
in all touched drivers. I plan to do this everywhere in the future, and
most relevant lines in the touched drivers are already modified by this

This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.
The drivers that didn't need this flag were:
drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c
The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.
Eventually this flag should go and it should not be used in new drivers.
There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).
It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.
For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.
While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.
I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

Rather than testing whether an ioctl is implemented in the driver or not
every time the ioctl is called, do it upfront when the device is registered.
This also allows a driver to disable certain ioctls based on the capabilities
of the detected board, something you can't do today without creating separate
v4l2_ioctl_ops structs for each new variation.
For the most part it is pretty straightforward, but for control ioctls a flag
is needed since it is possible that you have per-filehandle controls, and that
can't be determined upfront of course.

Using the V4L2 core lock is a very robust method that is usually very good
at doing the right thing. But some drivers, particularly USB drivers, may
want to prevent the core from taking the lock for specific ioctls, particularly
buffer queuing ioctls.
The reason is that certain commands like S_CTRL can take a long time to process
over USB and all the time the core has the lock, preventing VIDIOC_DQBUF from
proceeding, even though a frame may be ready in the queue.
This introduces unwanted latency.
Since the buffer queuing commands often have their own internal lock it is
often not necessary to take the core lock. Drivers can now say that they don't
want the core to take the lock for specific ioctls.
As it is a specific opt-out it makes it clear to the reviewer that those
ioctls will need more care when reviewing.

V4L2 uses the enum type in IOCTL arguments in IOCTLs that were defined until
the use of enum was considered less than ideal. Recently Rémi Denis-Courmont
brought up the issue by proposing a patch to convert the enums to unsigned:
<URL:http://www.spinics.net/lists/linux-media/msg46167.html>
This sparked a long discussion where another solution to the issue was
proposed: two sets of IOCTL structures, one with __u32 and the other with
enums, and conversion code between the two:
<URL:http://www.spinics.net/lists/linux-media/msg47168.html>
Both approaches implement a complete solution that resolves the problem. The
first one is simple but requires assuming enums and __u32 are the same in
size (so we won't break the ABI) while the second one is more complex and
less clean but does not require making that assumption.
The issue boils down to whether enums are fundamentally different from __u32
or not, and can the former be substituted by the latter. During the
discussion it was concluded that the __u32 has the same size as enums on all
archs Linux is supported: it has not been shown that replacing those enums
in IOCTL arguments would break neither source or binary compatibility. If no
such reason is found, just replacing the enums with __u32s is the way to go.
This is what this patch does. This patch is slightly different from Remi's
first RFC (link above): it uses __u32 instead of unsigned and also changes
the arguments of VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY.

When applications modify preview engine parameters, the new values are
applied to the hardware by the preview engine interrupt handler during
vertical blanking. If the parameters are being changed when the
interrupt handler is called, it just delays applying the parameters
until the next frame.
If an application modifies the parameters for every frame, and the
preview engine interrupt is triggerred synchronously, the parameters are
never applied to the hardware.
Fix this by storing new parameters in a shadow copy, and switch the
active parameters with the shadow values atomically.
