From: Hans Verkuil <[email protected]>
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.
Regards,
Hans
