2016-07-19[media] cec: limit the size of the transmit queueHans Verkuil
The size of the transmit queue was unlimited, which meant that in non-blocking mode you could flood the CEC adapter with messages to be transmitted. Limit this to 18 messages. Also print the number of pending transmits and the timeout value in the status debugfs file.

2016-06-28[media] cec: add HDMI CEC framework (core)Hans Verkuil
The added HDMI CEC framework provides a generic kernel interface for HDMI CEC devices. Note that the CEC framework is added to staging/media and that the cec.h and cec-funcs.h headers are not exported yet. While the kABI is mature, I would prefer to allow the uABI some more time before it is mainlined in case it needs more tweaks. This adds the cec-core.c, media/cec.h and cec-priv.h sources.
