The subject of the patch should contain "dss-of", not "of-dss". Although
for both patches I think it's fine to use plain "OMAPDSS: " prefix. The
subject should also say "fix" or such.

The description above is kind of "detached". A patch description should
generally describe something in the lines of what the current behavior
is, what the problem is, and what the patch does. And the desc should be
independent of the subject.

This particular case is rather simple, and it's clear that
dss_of_port_get_parent_device() is not supposed to decrease the refcount
of the "port" parameter (as that kind of behavior is normally a special
case). And so it should be enough to say what the issue seen is and that
you fix the function to not decrement the parameter's refcount.
