videobuf2 has long been subject to AB-BA style deadlocks due to the
queue lock and mmap_sem being taken in different orders for the mmap

without taking the queue lock, using an mmap_lock internal to videobuf2.

held, resulting in a potential deadlock. As the operation can now be
called without locking the queue, fix it.

While all other pad ops allow you to select whether to use the 'try' or

'try'.
However, this will fail if a simple (e.g. PCI) bridge driver wants to use
the enum pad op of a subdev that's also used in a complex platform driver
like the omap3. Such a bridge driver generally wants to enum formats based
on the active format.

[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

This patch introduces a new mutex at the struct uvc_video level and

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).

a lock. Commit f035eb4e976ef5a059e30bc91cfd310ff030a7d3 fixed a AB-BA

[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
