media: cec: use call_op and check for !unregistered
[ Upstream commit e2ed5024 ] Use call_(void_)op consistently in the CEC core framework. Ditto for the cec pin ops. And check if !adap->devnode.unregistered before calling each op. This avoids calls to ops when the device has been unregistered and the underlying hardware may be gone. Signed-off-by:Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by:
