Pull i2c updates from Wolfram Sang:
- Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes.
This avoids deadlocks/workarounds when the mux itself needs i2c
commands for muxing. And as a side-effect, other workarounds in the
media layer could be eliminated. Also, Peter stepped up as the i2c
mux maintainer and will keep an eye on these changes.
- major updates to the octeon driver
- add a helper to the core to generate the address+rw_bit octal and
make drivers use it
- quite a bunch of driver updates

"A revert fixing a breakage that caused an OOPS on all VB2-based DVB
drivers.
We already have a proper fix, but it sounds safer to keep it being
tested for a while and not hurry, to avoid the risk of another
regression, specially since this is meant to be c/c to stable. So,
for now, let's just revert the broken patch"

Revert "[media] videobuf2-v4l2: Verify planes array in buffer dequeueing"
When building the exynos-gsc driver with CONFIG_OF disabled, we get
a warning about an out-of-bounds access:
drivers/media/platform/exynos-gsc/gsc-core.c: In function 'gsc_probe':
drivers/media/platform/exynos-gsc/gsc-core.c:1078:34: error: array subscript is above array bounds [-Werror=array-bounds]
This is harmless because the driver will never be used without CONFIG_OF,
but it's better to avoid the warning anyway. Checking the return value
of of_alias_get_id() for an error condition is probably a good idea
anyway, and it makes sure the compiler can verify that we don't get
into that situation.

The tvp5150_write() function calls i2c_smbus_write_byte_data() that
can fail but does not propagate the error to the caller. Instead it
just prints a debug, so callers can't know if the operation failed.
So change the function to return the error code to the caller so it
knows that the write failed and also print an error instead of just
printing a debug information.
While being there remove the inline keyword from tvp5150_write() to
make it consistent with tvp5150_read() and also because it's called
in a lot of places, so making inline is in fact counter productive
since it makes the kernel image size to be much bigger (~16 KiB).

This patch adds support only for the first tuner.
The demodulator needs firmware, available for example here:

- Add a check for the case that both the cropcap and g_selection ops
are NULL. This shouldn't happen, but I feel happier if the code
guards against this.
- If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error
codes from cropcap. Just assume square pixelaspect ratio in that
case. This situation can happen if the bridge driver's cropcap op
calls the corresponding subdev's op. So the cropcap ioctl is set,
but it might return ENOIOCTLCMD anyway. In the past this would
just return an error which is wrong.
- Call cropcap first and let g_selection overwrite the bounds and
defrect. This safeguards against subdev cropcap implementations
that set those rectangles as well. What g_selection returns has
priority over what such cropcap implementations return.

The root i2c adapter lock is then no longer held by the i2c mux during
accesses behind the i2c gate, and such accesses need to take that lock
just like any other ordinary i2c accesses do.
So, declare the i2c gate mux-locked, and zap the regmap overrides
that makes the i2c accesses unlocked and use plain old regmap
accesses. This also removes the need for the regmap wrappers used by
rtl2832_sdr, so deconvolute the code further and provide the regmap
handle directly instead of the wrapper functions.
