because the driver tda18271 will use it to enable or disable the i2c-bus
from the demodulator to the tuner.
And thus eliminate the error message: "Unknown device (255) detected
@ 1-00c0, device not supported" in the driver tda18271.
In the device kworld_sbtvd (hybrid analog and digital TV) the control
of the i2c-bus to tuner is done in the analog demodulator and not in
the digital demodulator.

[media] rc-core: move timeout and checks to lirc
The lirc TX functionality expects the process which writes (TX) data to
the lirc dev to sleep until the actual data has been transmitted by the
hardware.
Since the same timeout calculation is duplicated in more than one driver
(and would have to be duplicated in even more drivers as they gain TX
support), it makes sense to move this timeout calculation to the lirc
layer instead.
At the same time, centralize some of the sanity checks.

[media] DVB: improve handling of TS packets containing a raised TEI bit
When the TEI bit is raised, we should not trust any of the contents of
the packet in question, including but not limited to its PID number.
Considering that we don't trust the PID number of this packet, we should
not proceed to check the packet counter (if dvb_demux_tscheck is set).
We should expect to see at least one discontinuity after a bad packet is
received, so any time a TEI is detected, a following TS packet counter
mismatch is to be expected.
There is no real reason to ever allow bad packets to pass through the
kernel demux, other than for purposes of attempting error correction via
software or statistical information.
However, since we have always passed these bad packets though the demux,
we should not change this default behavior.
Without altering module options, this patch merely prevents the
TS packet counter check on packets containing a raised TEI.
If module option dvb_demux_feed_err_pkts is set to 0, the kernel demux
will drop these error packets entirely, preventing any possibility of
corruption caused by userspace programs that are expecting valid data.

- Adopt to the changes that has happen in the kernel during the past
five years, such as the change in the include paths
- The OMAP DM-timers require much more care nowadays. The timers need
to be enabled and disabled or otherwise many actions fail. Timers

This driver adds support for stk1160 usb bridge as used in some
video/audio usb capture devices.
It is a complete rewrite of staging/media/easycap driver and
it's meant as a replacement.
As stk1160 allows communication with an ac97 codec chip, this
driver allows to register a control-only sound card to allow the user
to access ac97 controls.
Two devices have been used for testing:
* 1-cvbs video and 1-audio ac97 input,
* 4-cvbs inputs
Both of these devices reports with the same id [05e1:0408],
so the driver tries to support a superset of the capabilities.
By using keep_buffers module parameter it's possible to prevent
the driver from releasing urb buffers when streaming is stopped.
The usage of this parameter can avoid memory fragmentation that may
cause the driver to stop working on low memory systems.
A similar mechanism is implemented in em28xx driver (see commit 86d38d).
