Subject: [PATCH] video: fbdev: neofb.c: Cleaning up variable that is never used
Date: Sat, 05 Jul 2014 12:34:48 +0000 [thread overview]
Message-ID: <1404563688-20603-1-git-send-email-rickard_strandqvist@spectrumdigital.se> (raw)
From: Rickard Strandqvist <rickard.strandqvist@sonymobile.com>
Variable ar assigned a value that is never used.
I have also removed all the code that thereby serves no purpose.
This was found using a static code analysis program called cppcheck
