Dan, I'm so glad to see another like minded person on the topic. It
seems that we're a minority though :-(
Enric, if you want to increase the chances of this getting reviewed I
would humbly suggest adding a per-patch changelog (must), explicitly
Cc (in the commit message) the people who commented on your patch
(highly recommended), and perhaps cutting down the 20+ people from the
To/Cc list (nitpicking).
Another option would be to assist/review similar (drm bridge) patches
for other contributors, who should return with the same :-)
Just some suggestions (my 2c as they say), seeing that this has been
around for a while.
Regards,
Emil
