As spotted by Dan Carpenter (thanks!), we have
improperly used an unsigned variable in a calculation that may result in a
negative number. This may cause an unintended underflow if the interface
frequency of the tuner is > approx. 40MHz.
This patch should resolve the issue, following an approach similar to what is
used in af9013.c.[crope@iki.fi: add Reported-by]

recent patch with commit id 4f996594ceaf6c3f9bc42b40c40b0f7f87b79c86

As em28xx-dvb will always be initialized asynchronously, there's
no need anymore for a separate thread to load the DRX-K firmware.Fixes a known regression with kernel 3.6 with tda18271 driver
and asynchronous DRX-K firmware load.Antti tested it with the following hardware:

Due to udev-182, the firmware load was changed to be async, as
otherwise udev would give up of loading a firmware.Add an option to return to the previous behaviour, async firmware
loads cause failures with the tda18271 driver.Antti tested it with the following hardware:
Hauppauge WinTV HVR 930C

em28xx-dvb, em28xx-alsa and em28xx-ir are typically initialized
asyncrhronously. The exception for it is when those modules
are loaded before em28xx (or before an em28xx card insertion) or
when they're built in.Make the extentions to always load asynchronously. That allows
having all DVB firmwares loaded synchronously with udev-182.Antti tested it with the following hardware:

Until now, if there is a read error in tda18271_get_id, the driver
reports "Unknown device..." Instead, check the return value of
tda18271_read_regs and display the appropriate error message.Signed-off-by: Michael Krufky

if the configuration option 'delay_cal' is set, delay both IR & RF
calibration until init() is called.
both module option 'cal' or configuration option 'rf_cal_on_startup'
will override this delay. it makes no sense to mix 'delay_cal' with
'rf_cal_on_startup' as these options conflict with each other.Signed-off-by: Michael Krufky

The mixer video node supports only multi-planar API so the driver
should not be setting V4L2_CAP_VIDEO_OUTPUT flags. Fix this and
also switch to device_caps. Additionally fix the VIDIOC_ENUM_FMT
ioctl handler which now works for V4L2_BUF_TYPE_CAPTURE, rather
than expected V4L2_BUF_TYPE_CAPTURE_MPLANE.Signed-off-by: Sylwester Nawrocki

In order to reuse the FIMC-LITE module on Exynos4 and Exynos5
SoC introduce a set of callbacks for the media pipeline control
from within FIMC/FIMC-LITE video node. It lets us avoid symbol
dependencies between FIMC-LITE and the whole media device driver,
which simplifies the initialization sequences and doesn't
introduce issues preventing common kernel image for exynos4 and
exynos5 SoCs.
This patch also corrects following build errors:
drivers/built-in.o: In function `buffer_queue':
drivers/media/video/s5p-fimc/fimc-lite.c:414: undefined reference
to `fimc_pipeline_s_stream'

Ensure that unnecessary features are powered down at the end of the
attach() function on attach of the tuner's first instance. If the
configuration requires the loop thru or xtout features, they will
remain enabled.
This must *only* be done after attaching the first instance of the tuner.
If there are multiple instances of the tuner, the bridge driver will need
to maintain power managament by itself.Signed-off-by: Michael Krufky

The VBI capture for the decoder (/dev/vbi8) is special in that it captures
the VBI stream embedded in an MPEG stream that is being decoded.

they make no sense for such a device, and v4l2-compliance will complain
about that.Signed-off-by: Hans Verkuil
