Usually I try to show that by picking either Reviewed-by (I'm confident
the changes are fine) or Acked-by (Changes look sane, but I don't know
the code base and/or hardware good enough to be sure).

Yep.  Same for me when looking at patches for other drivers.  I think
this is one reason why it isn't that easy to get patches for drivers
reviewed where effectively only a single maintainer/developer is working
on.

Updated the commit message.
