1bbab525b6 media: cxusb: restore RC_MAP for MyGica T230
Commit f8585ce655 ("[media] dvb-usb-cxusb: Geniatech T230C support")
sneaked in an unrelated change for the older T230 (not C) model.

As the commit was reverted this change was reverted too,
although likely correct.

This reverts commit f8585ce655.

The T230C is handled by the dvb-usb-v2/dvbsky.c driver, which should
be preferred over a dvb-usb (v1) driver.

ad32495b15 media: em28xx-dvb: simplify DVB module probing logic
The module probing logic there is a way more complex than
it should be, and requires some special magic to avoid
stack overflows when KASAN is enabled.

Solve it by creating ancillary functions to setup the
platform data and request module.

Now, the probing functions are cleaner and easier to understand.

As a side effect, the size of the module was reduced by
about 9.7% on x86_64:

Before this patch:
   text	   data	    bss	    dec	    hex	filename
  51090	  14192	     96	  65378	   ff62	drivers/media/usb/em28xx/em28xx-dvb.o

The dvb_attach()/dvb_detach() methods are ugly hacks designed
to keep using the I2C low-level API. The proper way is to

Several modules were already converted to use it. Yet,

duplicated.

	- dvb_module_release()

f410b4093f media: em28xx: split up em28xx_dvb_init to reduce stack size
With CONFIG_KASAN, the init function uses a large amount of kernel stack:

drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init.part.4':
drivers/media/usb/em28xx/em28xx-dvb.c:2061:1: error: the frame size of 3232 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Using gcc-7 with -fsanitize-address-use-after-scope makes this even worse:

drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init':
drivers/media/usb/em28xx/em28xx-dvb.c:2069:1: error: the frame size of 4280 bytes is larger than 3072 bytes [-Werror=frame-larger-than=]

By splitting out each part of the switch/case statement that has its own local
variables into a separate function, no single one of them uses more than 500 bytes,
and with a noinline_for_stack annotation we can ensure that they are not merged
back together.

As configured currently, modulation in the driver is set to auto detect,
no matter what the user sets modulation to. This leads to both QAM64
and QAM256 having the same effect. QAM AUTO is explicitly added here for
compatibility with scanning software who can use AUTO instead of doing
essentially the same scan twice.
Also included is a module option to enforce a specific QAM modulation if
desired. The true modulation is read before calculating the snr.
Changes are backwards compatible with current behaviour.

5b3a8e9069 media: lgdt3306a: Set fe ops.release to NULL if probed
If release is part of frontend ops then it is called in the
course of dvb_frontend_detach. The process also decrements
the module usage count. The problem is if the lgdt3306a
driver is reached via i2c_new_device, then when it is
eventually destroyed remove is called, which further
decrements the module usage count to negative. After this
occurs the driver is in a bad state and no longer works.
Also fixed by NULLing out the release callback is a double
kfree of state, which introduces arbitrary oopses/GPF.
This problem is only currently reachable via the em28xx driver.

transfer mode is 256 * 188 bytes. This changes the size of bulk transfers
to maximum supported value and have a bonus beneficial alignment.

7aa92c4229 media: ABS macro parameter parenthesization
Replace usages of the locally defined ABS() macro with calls to the
canonical abs() from kernel.h and remove the old definitions of ABS()

This change was originally motivated by two local definitions of the
ABS (absolute value) macro that fail to parenthesize their parameter
properly. This can lead to a bad expansion for low-precedence
expression arguments.

For example: ABS(1-2) currently expands to ((1-2) < 0 ? (-1-2) : (1-2))
which evaluates to -3. But the correct expansion would be
((1-2) < 0 ? -(1-2) : (1-2)) which evaluates to 1.

The MaxLinear MxL5xx has support for physical layer scrambling, which was
recently added to the DVB core via the new scrambling_sequence_index
property. Add required bits to the mxl5xx driver.

Picked up from dddvb master, commit 5c032058b9ba ("add support for PLS")
by Ralph Metzler <rjkm@metzlerbros.de>, adapted to the different naming
of the pls property (pls vs. scrambling_sequence_index).

ed3056f015 media: media.h: reorganize header to make it easier to understand
The media.h public header is very messy. It mixes legacy and 'new' defines
and it is not easy to figure out what should and what shouldn't be used. It
also contains confusing comment that are either out of date or completely
uninteresting for anyone that needs to use this header.

The patch groups all entity functions together, including the 'old' defines
based on the old range base. The reader just wants to know about the available
functions and doesn't care about what range is used.

All legacy defines are moved to the end of the header, so it is easier to
locate them and just ignore them.

The legacy structs in the struct media_entity_desc are put under
also a much more effective signal to the reader that they shouldn't be used
compared to the old method of relying on '#if 1' followed by a comment.

The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header
in the legacy area. They are also dropped from intf_type() in media-entity.c.

All defines are also aligned at the same tab making the header easier to read.

9f564184e6 media: i2c: adv748x: fix HDMI field heights
The ADV748x handles interlaced media using V4L2_FIELD_ALTERNATE field
types.  The correct specification for the height on the mbus is the
image height, in this instance, the field height.

The AFE component already correctly adjusts the height on the mbus, but
the HDMI component got left behind.

Adjust the mbus height to correctly describe the image height of the
fields when processing interlaced video for HDMI pipelines.

1b3963509a media: cec: improve debugging
cec_transmit_msg_fh() first checked the message for errors, and only
after the message was found to be valid did it log the message contents.

However, that makes it hard to associate an error in the kernel log with
the message since the message contents was never logged in that case.

So swap the order: first log the message (once some very basic checks
are done), and only after that check for errors.

Fixes vb2_vmalloc_get_userptr() to ioremap correct area.
Since the current code does ioremap the page address, if the offset > 0,
it does not do ioremap the last page and results in kernel panic.

This fixes to pass the size + offset to ioremap so that ioremap
can map correct area. Also, this uses __pfn_to_phys() to get the physical
address of given PFN.

If buffers were prepared or queued and the buffers were released without
starting the queue, the finish mem op (corresponding to the prepare mem
op) was never called to the buffers.

Before commit a136f59c0a there was no need to do this as in such a case
the prepare mem op had not been called yet. Address the problem by
explicitly calling finish mem op when the queue is stopped if the buffer
is in either prepared or queued state.

and also exit with the error -ENOSYS to avoid the later out-of-bounds
array read.
