The new control mechanism uses dynamic control values in the subdriver
descriptor. It simplifies standard control handling.

XU control information is supposed to be entirely discoverable using
standard UVC queries. As some devices report bogus information (such as
reporting a read-only control as being read-write), add a fixup table
for XU controls.
This table can also be used to selectively disable requests supposed to
be supported by all XU controls (GET_MIN, GET_MAX, GET_DEF, GET_RES) but
not correctly (or at all) supported by the device.
The table currently disables GET_CUR on the Logitech motor control XU
pan/tilt controls.

XU controls initialization requires querying the device for control
information. As some buggy UVC devices will crash when queried
repeatedly in a tight loop, delay XU controls initialization until first
use.

Now that control information structures are not shared between control

This patch removes the sysadmin requirements for UVCIOC_CTRL_MAP (and the stub
implementation of UVCIOC_CTRL_ADD). This requirement no longer makes sense with
the new XU control access mechanisms since XU controls can be accessed without
adding control mappings first.
A maximum number (currently 1024) of control mappings per device is enforced to
avoid excess memory consumption caused by careless user space applications.

Devices advertise XU controls using a bitmask, in which each bit
corresponds to a control. The control selector, used to query the
control, isn't available in the USB descriptors.
All known UVC devices use control selectors equal to the control bit
index plus one. Hardcode that relationship in the driver, making the
UVCIOC_CTRL_ADD ioctl obsolete. All necessary information about XU
controls can be obtained by the driver at enumeration time.
The UVCIOC_CTRL_ADD ioctl is still supported for compatibility reasons,
but now always returns -EEXIST.
Finally, control mappings are now on a per-device basis and no longer
global.
As this changes the userspace interface, bump the driver version number
to 1.0.0 (it was about time).

The bandwidth estimate computed with the FIX_BANDIWDTH quirk is too low
for many cameras. Don't use maximum packet sizes lower than 1024 bytes
to try and work around the problem. According to measurements done on
two different camera models, the value is high enough to get most
resolutions working while not preventing two simultaneous VGA streams at
15 fps.

Don't hold the lock before unregistering the device, since when the
device is unregistered the datastruct containing the lock may be freed
(if the refcount went to 0).
Also fixed the framework documentation that erroneously suggested the
wrong locking order as well.

The AVerTV Red HD+ (A850T) is basically the same as the existing
AVerTV Volar Black HD (A850), but is specific to the french market.
The A850T identifies itself as a A850, but has its own PID. It even
suffers from the same EEPROM deficiencies.
This is based off a collection of information gathered from the
french support forums for Ubuntu, which I tried to properly format
into this patch:

Instead of doing its own lock, use core-assisted one. As a bonus, it
will do the proper unlock during queue wait events. This fixes a

This file came originally from cx23885 driver. Some functions aren't
used. Now that they are declared as static, we have those errors:

the git logs or from the cx23885 driver.

gcc didn't like to have i++ inside a complex operation:
drivers/media/video/cx231xx/cx231xx-417.c: In function ‘cx231xx_load_firmware’:
drivers/media/video/cx231xx/cx231xx-417.c:1059: warning: operation on ‘i’ may be undefined

drivers/media/video/cx231xx/cx231xx-417.c:1063: warning: operation on ‘i’ may be undefined
Btw, I agree with gcc, as we're using i and i++ at the same operation and,
depending on how optimization may occur, it may produce a wrong code.
While here, fix CodingStyle issues on the changed code.

The patches received from the vendor contained a lot of CodingStyle
issues. Cleans the style issues reported by checkpatch.pl on
those drivers.
It is better to do such style fixes when merging a big set of
changes than latter. Of course, the better is to receive patches
already cleaned ;)

By default, tda18271 tries to optimize I2C bus by updating all registers
at the same time. Unfortunately, some devices doesn't support it.
The current logic has a problem when small_i2c is equal to 8, since there
are some transfers using 11 + 1 bytes.
Fix the problem by enforcing the max size at the right place, and allows
reducing it to max = 3 + 1.
