* [PATCH] video: fbdev: omap2: dss: hdmi5_core.c: Cleaning up variable that is never used
From: Rickard Strandqvist @ 2014-07-05 12:41 UTC (permalink / raw)
To: Jean-Christophe Plagniol-Villard, Tomi Valkeinen
Cc: Rickard Strandqvist, Rickard Strandqvist, Jyri Sarha, linux-fbdev,
linux-kernel
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
