media: cec-adap.c: drop activate_cnt, use state info instead
[ Upstream commit f9222f8c ] Using an activation counter to decide when the enable or disable the cec adapter is not the best approach and can lead to race conditions. Change this to determining the current status of the adapter, and enable or disable the adapter accordingly. It now only needs to be called whenever there is a chance that the state changes, and it can handle enabling/disabling monitoring as well if needed. This simplifies the code and it should be a more robust approach as well. Signed-off-by:Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by:
