media: cec: copy sequence field for the reply

2021-11-10T11:39:08+00:00

When the reply for a non-blocking transmit arrives, the sequence
field for that reply was never filled in, so userspace would have no
way of associating the reply to the original transmit.

Copy the sequence field to ensure that this is now possible.

media: CEC: keep related menu entries together

2021-10-05T07:39:32+00:00

Keep all of the CEC menu items grouped together.
By grouping all of these menu entries inside a menu/endmenu block,
they are forced to be kept together and they are displayed/presented
in a group for users.

Tested with xconfig, gconfig, menuconfig, and nconfig.

media: cec-pin: fix off-by-one SFT check

2021-09-30T08:07:54+00:00

The CEC pin framework has to wait for the CEC bus to be idle for the
requested Signal Free Time before it can start a transmit.

However, the check for that was off by one, so transmits would start one
bit period (2.4ms) too late.

The cec pin timer overruns are measured in microseconds, but the variable
names include the millisecond symbol "ms". To avoid confusion, replace
"ms" with "us" in the variable names and printed status message.

patch fixes that.
