Subject: media: cec: copy sequence field for the reply
Author:  Hans Verkuil <hverkuil-cisco@xs4all.nl>
Date:    Tue Nov 2 12:24:26 2021 +0000

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.
