Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.
Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().
Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

This patch is on behalf of Stephen Backway <stev391@email.com>, and
represents two patches I received (and some subsequent whitespace
cleanup I had due to how I pulled the patches).
From the original author:
a) Add DVB support for the Leadtek Winfast PxDVR3200 H.
b) The tuner callback previously checked the command 3 times:
1) To see if it was the XC2028_RESET_CLK
2) To see if it was not the XC2028_RESET_TUNER
3) To see if it was the XC2028_RESET_TUNER
This patch removes the third check.

A simple state machine was added to saa7134_ts. It has three states:
SAA7134_TS_STOPPED
SAA7134_TS_BUFF_DONE
SAA7134_TS_STARTED
When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED.
When all buffers are prepared we write data into DMA register and set
SAA7134_TS_BUFF_DONE.
When the first buffer is active start TS and set SAA7134_TS_STARTED.
When ts_release is called stop TS and set SAA7134_TS_STOPPED.

The driver_data field of the device structure was zeroed, thus losing

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

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.
