media: cec-pin: add 'received' callback
Drivers that use the CEC pin framework have no way of processing messages themselves by providing the 'received' callback. This is present in cec_ops, but not in cec_pin_ops. Add support for this callback. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
