Fix zoom controls of older version of Waltop Media Tablet 10.6 inch, aka
Genius G-Pen M609. This should make it supported on par with the newer
version, aka Genius G-Pen M609X.
The fix is extrapolated from the behavior of the newer version (Genius G-Pen
M609X) and both older and newer versions of Media Tablet 14.1 inch (Genius
G-Pen M712/M712X) and should work with high probability.

Commit bd25f4dd69 ("HID: hiddev: use usb_find_interface,

purpose of storing hiddev pointer.
This is a problem, because intf pointer is already being set to struct
hid_device pointer by HID core. This obviously lead to memory corruptions
at device disconnect time, such as
WARNING: at lib/kobject.c:595 kobject_put+0x37/0x4b()
kobject: '(null)' (ffff88011e9cd898): is not initialized, yet kobject_put() is being called.
Convert hiddev into accessing hiddev through struct hid_device which is

Many tablet input drivers use BTN_STYLUS2 code to report a second
tablet stylus button. Yet, the generic HID input driver doesn't map it.
Apparently, because there is no corresponding usage in the HID Usage Tables.
This patch selects a compromise usage - "Tablet Pick" (0x46) to be mapped to
BTN_STYLUS2. Some tablets use "Eraser" usage, but mapping it to a button
wouldn't be entirely correct, because the specification says it may be "a

This removes the private hiddev_table in the usbhid
driver and changes it to use usb_find_interface
instead.
The advantage is that we can avoid the race between
usb_register_dev and usb_open and no longer need the
big kernel lock.
This doesn't introduce race condition -- the intf pointer could be
invalidated only in hiddev_disconnect() through usb_deregister_dev(),
but that will block on minor_rwsem and not actually remove the device
until usb_open().

Reallocating memory in depth change does not work well if some
userspace application has mmapped() the framebuffer as that mapping
does not get adjusted (thus application continues to write to old
buffer).
In addition doing deferred_io_cleanup() and init() inside of set_par()
tends to deadlock with fbcon's flashing cursor.

and just use 1/8 of it while running at 1bpp.

The new scroll_speed param takes an integer value from 0 to 63, where 0
is slowest and 63 is fastest. The default of 32 remains the same. This
parameter also affects scroll acceleration linearly.
A second part of this change is a tightly coupled modification to the
scroll acceleration. Previously, scroll acceleration could be reset
without lifting the scroll finger. This is rather unintuitive and hard
to control in the case where a user wants faster scrolling, but wants to
hold the scroll touch for longer than a moment.
Note that scroll acceleration levels are now 1-7, where 7 is slowest. In
the previous implementation, there were 8 levels defined, but it was
impossible to start at the slowest level. In order to keep the default
scroll speed unchanged, only 7 levels are used now.

The whole point of making some of the drivers automatically selected
unless 'EMBEDDED' was to handle quirks transparently after their separation
from the generic core.
Over time, some of the later-added quirks grew into more standalone drivers,
implementing non-trivial features a being larger than a few bytes of code.
In addition to that, some of the standalone drivers don't make sense for
99.9% of the users, as they are very specific to rare devices.
Therefore build by default in only those drivers which
- we historically used to support even before quirk separation from the
core code
- are isolated enough and likely to hit quite large portion of the
users anyway (Microsoft, Logitech)

For more clearance what the functions actually do,
usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()
They should only be used in code which really needs DMA coherency.
All call sites have been changed accordingly, except for staging
drivers.

This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers. There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical). Furthermore, only seven
drivers used it. We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.
The DMA-mapping portion of hcd.c is currently in flux. A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down. The removal should go smoothly,
as by then nobody will be using it.

This patch makes the hidraw driver use the first Interrupt OUT endpoint for
HID transfers to the device if such an endpoint exists. This is consistent
with the behavior of the hiddev driver, and the logic is similar.
From the USB HID specification:
The Interrupt Out pipe is optional. If a device declares an Interrupt Out
endpoint then Output reports are transmitted by the host to the device
through the Interrupt Out endpoint. If no Interrupt Out endpoint is
declared then Output reports are transmitted to a device through the
Control endpoint, using Set_Report(Output) requests.

The skip label frees resp, which has not been allocated at the point of
this goto and then does a break, based on the fact that err is non-zero.
This is replaced by a break directly.

When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has
claimed the magicmouse device, and probe routine bails out. Which is not what we want.
This happens because magicmouse driver is instantiating the connection to
Input subsystem itself, and since commit 28918c211d ("HID: magicmouse: fix
oops after device removal") the HID core is not registering input device
itself.
Fix this by letting HID core register the input device (so that hid_hw_start()
succeeds, as the device is claimed by at least one subsystem) and de-register
it again later before proceeding with proper input setup.
