'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

Checkpatch wants to use 'help' instead of '---help---':
WARNING: prefer 'help' over '---help---' for new help texts
Let's change it globally at the media subsystem, as otherwise people
would keep using the old way.

The CEC framework is used by both drm and media. That makes it tricky
to get the dependencies right.
This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options
out of the media menu and instead drivers that want to use CEC should
select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.
Move those sources to media/cec as well.
The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.
Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).
Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.
CEC drivers should now depend on CEC_CORE.
CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.
The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

It allows to simulate the behavior of hardware with such limitations or
to connect vivid to real hardware with such limitations.
Add the "allocators" module parameter option to let vivid use the
dma-contig instead of vmalloc.

The vivid driver has been extended to provide CEC adapters for the HDMI
input and HDMI outputs in order to test CEC applications.
This CEC emulation is faithful to the CEC timings (i.e., it all at a
snail's pace).

The vivid driver currently has a hard-coded limit of 64 devices,
however there's nothing that prevents the creation of even more devices.
This commit adds a new driver option (which defaults to 64) to
allow this maximum number to be configurable.
