[GIT PULL FOR v4.8] Fixes and updates (mostly cec-related) (v3)

[Hans Verkuil]

Hi Mauro,

These are (regression) fixes for 4.8, mostly related to the cec framework.

It fixes some dubious locking code, two typos in cec-funcs.h, a missing reply
for the Record On/Off messages, improves the documentation, adds a TODO line,
adds a flag to explicitly allow fallback to Unregistered, ensures unclaimed
LAs are set to INVALID, prevents broadcast messages from being processed
when they should be ignored and add a IEEE ID check when locating in physical
address location in the EDID.

The CEC_LOG_ADDRS_FL_ALLOW_UNREG_FALLBACK patch changes the default behavior,
so I would like to get that in for 4.8 rather than waiting for 4.9.

The cec-compliance test we've been working on is done and merged in v4l-utils.
This means we have 99% coverage (only some CDC HEC tests are missing since
that's rarely used). These patches fix some remaining problems that we've found
while working on this test.

I hope to fix the remaining items from the TODO list for 4.9 so that the
framework can be mainlined soon.

There are three other patches: the mediatek patch adds a missing HAS_DMA
dependency to shut the kbuild robot up, and there are two fixes for the pulse8-cec
driver. Many thanks to Pulse-Eight for providing me with the information
necessary for these two patches.

Regards,

	Hans
