The correct place to put i2c_gate_ctrl is before calling tda18271_attach,
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.

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.

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.

This patch fixes the following sparse warnings
by removing use of duplicate const.

drivers/media/video/cx88/cx88.h:152:40:
	warning: duplicate const
drivers/media/video/cx88/cx88-core.c:256:33:

drivers/media/video/cx88/cx88-alsa.c:769:41:

As commented by Jonathan Nieder:

	These double "const" were introduced in v2.6.37-rc1~64^2~464 (V4L/DVB:
	drivers/media: Make static data tables and strings const, 2010-08-25).

	The address of an array is already immutable by definition, so for
	what it's worth, with or without a clarified commit message,

This is the driver for the IR transmitter diode found on the Nokia
N900 (also known as RX51) device. The driver is mostly the same as
found in the original 2.6.28 based kernel that comes with the device.

The following modifications have been made compared to the original
driver version:

- 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
  must not be freed without first stopping them or otherwise the timer
  cannot be requested again.

The code has been tested with sending IR codes with N900 device
running Debian userland. The device receiving the codes was Anysee
DVB-C USB receiver.

This callback were meant to allow overriding a FE callback, before its
call, but it is not really needed, as the callback can be intercepted
after tuner attachment.

Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5
application will produce different effects than a DVBv3 one.

So, get rid of it.

calls ir_raw_event_handle() but before clearing ir->active, then the

The Pioneer CU-700 remote causes receiver overflows if you hold down any
button. The remote does not send NEC IR repeats, it repeats the entire
NEC code after 20ms.

The iguanair hardware advertises an interval of 10 which just not enough;
with 100 URBs per second and at most 7 edges per URB, we handle at most
700 edges per second. The remote generates about 900.
