Commit dc77523c5d ensured that m.offset is
only set for the MMAP memory mode by calling __setup_offsets only for that
mode.
However, __setup_offsets also initializes the length fields, and that should
be done regardless of the memory mode. Because of that change the v4l2-ctl
test application fails for the USERPTR mode.
This fix creates a __setup_lengths function that sets the length, and
__setup_offsets just sets the offset and no longer touches the length.

In order to avoid nesting mutexes the private mutex is taken after the

Currently it is not possible for userspace to map a DMABUF exported buffer
with write permissions. This patch allows to also pass O_RDONLY/O_RDWR when
exporting the buffer, so that userspace may map it with write permissions.

This mirrors the patch to the radio-shark driver by Geert Uytterhoeven.
If SHARK_USE_LEDS=1, but CONFIG_PM=n:
drivers/media/radio/radio-shark2.c:240: warning: ‘shark_resume_leds’ defined but not used
Instead of making the #ifdef logic even more complicated (there are already
two definitions of shark_resume_leds()), mark shark_resume_leds() inline to
kill the compiler warning. shark_resume_leds() is small and it has only one
caller.

The remote subdev of any video node in the OMAP3 ISP is an internal
subdev that is guaranteed to implement get_fmt. Don't check the return
value for -ENOIOCTLCMD, as this can't happen.
While at it, move non-critical code out of the mutex-protected section.

Commit 5aa9ae5ed5 inverted the mute control
state test in s_routing which caused the audio routing to fail. This broke
ivtv support for the Hauppauge video/audio input bracket (which adds additional
video and audio inputs) all the way back in kernel 2.6.36.
This fix fixes the condition and it also removes a nonsense check on the
balance control.

The no_video flag was checked in all other cases except one. Calling
v4l2_ctrl_handler_setup() if no_video is 1 will crash.
This wasn't noticed before since there are only two card types that
set no_video to 1, so this type of hardware is quite rare.
