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
depends on any other outstanding patches.

The status[] is part of  uvc_device structure. We can't make sure
the address of status is at a cache-line boundary in all archs,so
status[] might share a cache-line with some fields in uvc_structure.
This can lead to some cache coherence issues(http://lwn.net/Articles/2265/).

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.

For demod drivers, we want a single tuning function (set_frontend) to have
access to the properly constructed dvb_frontend_parameters structure, or
the cache values - regardless of whether the legacy or new API is being used.

This cuts down on redundant code in the demod drivers and ensures the
tuning parameters are consistent regardless of the API entry type.

After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
   switch to a flexible variable length API. For practical reasons
   a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
   of commands.

tune-v0.0.3.c is required to use this API, it contains the interface changes.
