[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config
If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.
This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.
The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.
One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.

Switch this driver over to the V4L2 core locking mechanism in preparation
for switching to unlocked_ioctl. Suggested by Laurent Pinchart.
This patch introduces a new mutex at the struct uvc_video level and
drops the old mutex at the queue level. The new lock is now used for all
ioctl locking and in the release file operation (the driver always has
to take care of locking in file operations, the core only serializes
ioctls).
Note that the mmap and get_unmapped_area file operations no longer take
a lock. Commit f035eb4e976ef5a059e30bc91cfd310ff030a7d3 fixed a AB-BA
deadlock by moving all the locking down into vb2, so the mmap and
get_unmapped_area file operations should no longer do any locking before
calling into vb2.

[media] vivid sdr: Use LUT based implementation for sin/cos()
The common implementation for sin/cos in include/linux/fixp-arith.h
has been improved recently to provide higher precision.
Replacing native implementation of sin/cos in vivid sdr with common
implementation. This serves two purposes:
1. Improved accuracy: the native implementation based on the Taylor
series is more prone to rounding errors.
2. Reuse of common function: this is better compared to maintaining
native versions for each driver.
[media] fixp-arith: replace sin/cos table by a better precision one
The cos table used at fixp-arith.h has only 8 bits of precision.
That causes problems if it is reused on other drivers.
As some media drivers require a higher precision sin/cos
implementation, replace the current implementation by one that
will provide 32 bits precision.
The values generated by the new implementation matches the
32 bit precision of glibc's sin for an angle measured in
integer degrees.
It also provides support for fractional angles via linear
interpolation. On experimental calculus, when used a table
with a 0.001 degree angle, the maximum error for sin is
0.000038, which is likely good enough for practical purposes.
There are some logic there that seems to be specific to the
usage inside ff-memless.c. Move those logic to there, as they're
not needed elsewhere.

We need to initialize the media controller earlier, as the core
will call the smsdvb hotplug during register time. Ok, this is
an async operation, so, when the module is not loaded, the media
controller works.
However, if the module is already loaded, nothing will be
registered at the media controller, as it will load too late.
Originally, sms_err() would be also displaying the line where
the error occurs, but the messages are clear enough. Also,
the function is always printed. So, no need for it.
[media] siano: add support for the media controller at USB driver
Adding support for the media controller for a pure DVB device
is simple: just create a struct media_device and add it to the
dvb adapter. After creating all DVB devices, we need to call
the DVB core, for it to create the media graph.
More work is needed for pure DVB tuners, but this is hidden
at the Siano driver, just like several others non-hybrid
devices. So, this is streight forward.
(in the above, dashes represent the enabled link, and periods
represent the disabled ones)
In other words, if we want to properly represent the pipeline,
it should be possible to see via the media controller if the tuner
is being used as an image source, or if the source is something else.
I didn't map those other inputs here yet, due to a few things:
- The extra inputs would require subdevs that won't be controlled
- I was in doubt about the best way for doing that
- That would likely require some extra setup for cx25840 caller
drivers, in order to represent what of the possible internal
inputs are actually used on each specific board
Actually, at least for now, I was unable to see much benefit
on adding such map now, so let's just document it, as this could
be added later on, as needed.

[media] media.h: mark alsa struct in media_entity_desc as TODO
The alsa struct in struct media_entity_desc is now marked as deprecated.
However, the alsa struct should remain as it is since it cannot be replaced
by a simple major/minor device node description. The alsa struct was designed
to be used as an alsa card description so V4L2 drivers could use this to expose
the alsa card that they create to carry the captured audio. Such a card is not
just a PCM device, but also needs to contain the alsa subdevice information,
and it may map to multiple devices, e.g. a PCM and a mixer device, such as the
au0828 usb stick creates.
This is exactly as intended and this cannot and should not be replaced by a
simple major/minor.
However, whether this information is in the right form for an ALSA device such
that it can handle udev renaming rules as well is another matter. So mark this
alsa struct as TODO and document the problems involved.
Updated the documentation as well to reflect this and to add the 'major'
and 'minor' field documentation.
Updated the documentation to clearly state that struct dev is to be used for
(sub-)devices that create a single device node. Other devices need their own
structure here.

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.
Big surprise.
But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?
In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.
Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.
