From: Hans Verkuil <hans.verkuil@xxxxxxxxx> The first patch adds new status flags to indicate when a pending message is aborted because the CEC adapter is unconfigured, and when a transmit times out (this indicates a driver bug). The second and third patch fix a minor issue with the adv HDMI receivers: if the EDID goes away, then the physical address also becomes invalid. The fourth patch fixes a race condition in the omap4 CEC driver that causes a transmit time out. The final patch drops the code in the omap4 CEC driver that attempts to set the number of retransmits: those register bits are read-only, so the code is pointless. There are no dependencies between these patches, although the first and fourth patch relate to the same problem. With the new transmit TIMEOUT status I hope that it will be easier to catch driver bugs like that earlier since this bug remained hidden for too long.
