When the input is set to tuner and no antenna is connected, the BT848
can flood VPRES interrupts. So we don't want to enable this type of
interrupts when the input it set to tuner.

As we don't do anything when receiving such an interrupt anyway, the
easiest fix is to simply not unmask this specific interrupt.

Replace the old register_chrdev with the more flexible register_chrdev_region.

Ensure that the release() is called when the very last chardev usage was
released, and not when the sysfs devices were removed. This should simplify
hotpluggable drivers considerably.

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.

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.
