Auto-update controls are never marked is loaded to prevent uvc_get_ctrl from
loading the control value from the cache. When setting a composite (mapped to
several V4L2 controls) auto-update UVC control, the driver updates the control
cache value before processing each V4L2 control, overwriting the previously
set V4L2 control.
This fixes the problem by marking all controls as loaded in uvc_set_ctrl
regardless of their type and resetting the loaded flag in uvc_commit_ctrl for
auto-update controls.

instead of register_chrdev", the internal reference count is no longer
necessary in order to free the internal stk_webcam struct. This patch
removes the reference counter from the stk_webcam struct and frees the
struct via the video_device release callback. It also fixes an
associated bug in stk_camera_probe which could result from
video_unregister_device being called before video_register_device.
Lastly, it simplifies access to the stk_webcam struct in several
places. This patch should apply cleanly against the "working" branch
of the v4l-dvb git repository.
This patch is identical to the patch I sent a couple of months back
titled "stk-webcam: Fix video_device handling" except that it has been
rebased against current modifications to stk-webcam and it no longer

From the author:
This patch-set fixes remote control issues I have experienced
with hauppauge drivers in Linux since the PVR-350 and now
with both a NOVA-S+ and HVR-4000. It has also been confirmed
to work with an HVR-1300 user who had exactly the same issue.
Hauppage remote controls use RC5. RC5 has a bit-field which
represents the target device. The hauppauge windows drivers
have a registry key which can enable filtering, but the linux
drivers will accept any target device in this bit field for
internal processing.
This causes problems with setups such as mythtv where remote
control key presses destined for the TV (target = 0) are
interpreted by the kernel and subsequenctly LIRC then mythtv.
Of the remote controls I have to hand (wintv black, pvr/hvr
silver) the hauppauge remotes send one of two device targets
ids, these are interpreted by the patch which then filters
out any non hauppauge addresses.

Add a second release function: video_device_release_empty
It can be used by drivers that have statically allocated
video_device structs.
Its use usually, but not always, indicates laziness on the
part of the driver programmer.

cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task
handles so we need to have it release the buffers associated with a task handle
at the end of a capture. If we don't, buffer ids used for one type of stream
in the driver (MPEG, TS, PCM), could be used for another type of stream by the
CX23418, if a previously used handle is assigned to a different type of stream.
The driver would drop valid buffers when this happened.

cx18: Fix cx18_find_handle() and add error checking. cx18_find_handle() did

When a suspended device has been reset instead of being resumed, USB core
calls the reset_resume method if available instead of unbinding and rebinding
the device.
This patch implements reset_resume by reusing the current resume
implementation and simplifies the resume method by skipping the controls
restore stage. Resuming from autosuspend should be faster.

This driver is for VERY old i2c-over-parallel port teletext receiver
boxes. Rather then spending effort on converting this driver to V4L2,
and since it is extremely unlikely that anyone still uses one of these
devices, it was decided to drop it (after discussing this as well with
the original author, Phil Blundell).

Old driver for the dpc7146 demonstration board that is no longer
relevant. The last time this was tested on actual hardware was
probably around 2002. Since this is a driver for a demonstration
board the decision was made (after discussing this with the original
author, Michael Hunold) to remove it rather than spending a
lot of effort continually updating this driver to stay in sync
with the latest internal V4L2 or I2C API.
