Some digging showed that a merge at some previous point partially
added broken mmap() support, causing this trace. Remove the broken
code completely.
On top of that, the calculation in place for "buffer full" depended on
UYUV instead of HM12, while our GStreamer code was picking HM12 in
some circumstances.
Finally, the V4L2_CAP_STREAMING capability was never exposed. Patch it
into the YUV encoder node only.

The initial version of this patch (commit
d5976931639176bb6777755d96b9f8d959f79e9e) had some issues:
* It didn't correctly calculate the size of the YUV buffer for 4:2:2,
resulting in capture sometimes being offset by 1/3rd of a picture.
* There were a lot of variables duplicating information the driver
already knew, which have been removed.
* There was an in-kernel format conversion - libv4l can do this one,
and is the right place to do format conversions anyway.
* Some magic numbers weren't properly explained.
Fix all these issues, leaving just the move from videobuf to videobuf2
to do.

discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c

The v4l core sets the v4l2_input.capabilities field based on the supplied
v4l2_ioctl_ops. However, several drivers do a memset or memcpy of the v4l2_input
struct, thus overwriting that field incorrectly.
Either remove the memset (which is already done by the v4l core), or add the
proper capabilities field in case of a memcpy.
The same is also true for v4l2_output, but that only affected the ivtv driver.

I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in
cx18 module and Andy Walls in ivtv mailing-list gave me some advice on
making a patch and sending it here. So here's the patch against
staging/2.6.37-rc1 branch (the tutorial recommends to include it as
plain text but if it's the case I can surely send as an attachment):
Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.

Video drivers request submodules using a work during probe and calls
flush_scheduled_work() on exit to make sure the work is complete
before being unloaded. This patch makes these drivers flush the work
directly instead of using flush_scheduled_work().
While at it, relocate request_submodules() call in saa7134_initdev()
right right before successful return as in other drivers to avoid
failing after the work is scheduled and returning failure without the
work still active.
This is in preparation for the deprecation of flush_scheduled_work().

With the v4l2_i2c_new_subdev* functions now supporting loading modules

The sub-devices without a listed module name don't result in and I2C
sub-device being created, as they either are IR devices or don't have an
I2C address listed. It's thus safe to rely on modaliases only.
