3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit d6daef95127e41233ac8e2d8472d8c0cd8687d38 upstream.
We assume that "pmic" could be NULL and then dereference it two lines
later. I fix this by moving the dereference inside the NULL check.
Fixes: c013f0a56c56 ('mfd: Add pm8xxx irq support')
