Subject: [PATCH] drm: omapdrm: silence unititialized variable warning
Date: Wed, 18 Apr 2018 17:29:37 +0300 [thread overview]
Message-ID: <20180418142937.GA13828@mwanda> (raw)
Smatch complains that "area_free" could be used without being
initialized. This code is several years old and premusably works fine
so this can't be a very serious bug. But it's easy enough to silence
the warning. If "area_free" is false at the end of the function then
we return -ENOMEM.
