From 529b315d6ae37f647f290a8ccc7a73befb32d1eb Mon Sep 17 00:00:00 2001

Subject: [PATCH 3958/4131] drm/amd/pp: silence a static checker warning
This has a static checker warning because "frev" and "crev" can be
uninitialized if "info" is NULL. I just changed the order of the checks
so that we check "info" first.
