[PATCH] pinctrl: Drop error prints on kzalloc() failure

From: Bjorn Andersson
Date: Thu Jan 05 2017 - 19:14:59 EST


Upon failing kzalloc() will print an error message in the log, so
there's no need for additional printouts. Also standardizes the "!ptr"
vs "ptr == NULL" while I'm touching those lines.

Hope you don't find this too OCD-ish.
