Subject: [PATCH] gpu: drm/gma500/mdfld_dsi_output.c: remove unnecessary null pointer check
Date: Tue, 15 Jan 2013 01:30:57 +0100 [thread overview]
Message-ID: <1358209863-16570-1-git-send-email-dinggnu@gmail.com> (raw)
the variable sender is dereferenced in line 95, so it is no reason to check
null again in line 99.
