No, sorry... :)
I wanted to say that _if_ we want this kind of change, then log_errno()
should not be a v4l2.c feature. But since I do not maintain log.c, I
cannot approve putting log_errno() there.
So, I think there are various questions:
1) Is log_errno() useful/wanted? I am undecided about this (other
people's opinions are welcome)
2) If the answer to 1) is yes, where should log_errno() go? My opinion
is "not in v4l2.c". I think log.c is more suitable.
3) If putting log_errno() in log.c is ok, would this implementation be
acceptable for the maintainer? (looks ok to me, but I do not maintain
log.c... This is why I mentioned you).
