H A D | cec-funcs.h | 9b211f9c Tue Oct 01 02:56:38 CDT 2019 Hans Verkuil <hverkuil-cisco@xs4all.nl> media: cec-funcs.h: add status_req checks
The CEC_MSG_GIVE_DECK_STATUS and CEC_MSG_GIVE_TUNER_DEVICE_STATUS commands both have a status_req argument: ON, OFF, ONCE. If ON or ONCE, then the follower will reply with a STATUS message. Either once or whenever the status changes (status_req == ON).
If status_req == OFF, then it will stop sending continuous status updates, but the follower will *not* send a STATUS message in that case.
This means that if status_req == OFF, then msg->reply should be 0 as well since no reply is expected in that case.
