[ Upstream commit cbe499977bc36fedae89f0a0d7deb4ccde9798fe ]
If, when waiting for a transmit to finish, the wait is interrupted,
then you might get a "transmit timed out" message, even though the
transmit was interrupted and did not actually time out.
Set transmit_in_progress_aborted to true if the
wait_for_completion_killable() call was interrupted and ensure
that the transmit is properly marked as ABORTED.

When cec_release() uses fh->msgs it has to take fh->lock,
otherwise the list can get corrupted.

commit ce5d241c3ad4568c12842168288993234345c0eb upstream.
The valid_la is used to check the length requirements,
including special cases of Timer Status. If the length is
shorter than 5, that means no Duration Available is returned,
the message will be forced to be invalid.
However, the description of Duration Available in the spec
is that this parameter may be returned when these cases, or
that it can be optionally return when these cases. The key
words in the spec description are flexible choices.
Remove the special length check of Timer Status to fit the
spec which is not compulsory about that.
