[media] media: ov13858: Fix 4224x3136 video flickering at some vblanks
Previously, with crop (0, 0), (4255, 3167), VTS < 0xC9E was resulting in
blank frames sometimes. This appeared as video flickering. But we need VTS
< 0xC9E to get ~30fps.
Omni Vision recommends to use crop (0,8), (4255, 3159) for 4224x3136. With
this crop, VTS 0xC8E is supported and yields ~30fps.

If you have a control handler that does not contain any controls, then
currently calling VIDIOC_G/S/TRY_EXT_CTRLS with count == 0 will return
-EINVAL in the class_check() function.
This is not correct, there is no reason why this should return an error.
The purpose of setting count to 0 is to test if the ioctl can mix controls
from different control classes. And this is possible. The fact that there
are not actually any controls defined is another matter that is unrelated
to this test.
This caused v4l2-compliance to fail, so that is fixed with this patch applied.

[media] rcar_drif: fix potential uninitialized variable use
Older compilers like gcc-4.6 may run into a case that returns
an uninitialized variable from rcar_drif_enable_rx() if that
function was ever called with an empty cur_ch_mask:
drivers/media/platform/rcar_drif.c:658:2: error: ‘ret’ may be used uninitialized in this function [-Werror=uninitialized]
Newer compilers don't have that problem as they optimize the
'ret' variable away and just return zero in that case.
This changes the function to return -EINVAL for this particular
failure, to make it consistent across all compiler versions.
In case gcc gets changed to report a warning for it in the
future, it's also a good idea to shut it up now.

[media] media: lirc_dev: merge struct irctl into struct lirc_dev
The use of two separate structs (lirc_dev aka lirc_driver and irctl) makes

tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic drivers
The patch simply replaces all msleep function calls with usleep_range calls
in the generic drivers.
Tested with an Infineon TPM 1.2, using the generic tpm-tis module, for a
thousand PCR extends, we see results going from 1m57s unpatched to 40s
with the new patch. We obtain similar results when using the original and
patched tpm_infineon driver, which is also part of the patch.
Similarly with a STM TPM 2.0, using the CRB driver, it takes about 20ms per
extend unpatched and around 7ms with the new patch.
Note that the PCR consistency is untouched with this patch, each TPM has
been tested with 10 million extends and the aggregated PCR value is
continuously verified to be correct.
As an extension of this work, this could potentially and easily be applied
to other vendor's drivers. Still, these changes are not included in the
proposed patch as they are untested.

The help text should be indented by at least two spaces after the

for building media drivers makes this assumption.
I went through all Kconfigs under drivers/media and fixed any bad help
sections. This makes it conform to the common practice and should fix
problems with 'make menuconfig' when using media_build. This is due to
a "WARNING" message that media_build can insert in the Kconfig and that
assumes the help text is indented by at least two spaces. If not, then the
Kconfig becomes invalid and 'make menuconfig' fails.

media: cobalt: do not register subdev nodes
In the distant past the adv7604 driver used private controls. In order
to access them the v4l-subdevX nodes were needed. Later the is_private
tag was removed in the adv7604 driver and the need for v4l-subdevX
device nodes disappeared.
Remove the creation of those device nodes from this driver.
Note: the cobalt card is only used inside Cisco and we never actually
used the v4l-subdevX nodes for anything. So this API change can be done
safely without breaking anything.
