    Subject[PATCH] video: backlight: ili922x.c: Cleaning up variable that is never used
    Date
    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
