[PATCH 00/12] Fix Unchecked return value from library errors

[Gedare Bloom]

separate all the grlib/gr device driver fixes, and submit them as a
separate patch set for review/approval by Daniel. We may need to
collect a set of these and poke him, but we want to make sure we keep
some consistency with them, in case they have any patches outside our
tree waiting to merge. (just a little bit of good citizenship)
