Subject: [PATCH] drm/amd/pp: silence a static checker warning
Date: Fri, 23 Mar 2018 11:39:03 +0000 [thread overview]
Message-ID: <20180323113903.GD28518@mwanda> (raw)
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.
