Subject: staging/xgifb: Remove duplicated code in loops.
X-Git-Tag: v3.9-rc1~127^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=771f3eed631be02b08544fc46cdfd2558599cf5d;p=profile%2Fivi%2Fkernel-x86-ivi.git

staging/xgifb: Remove duplicated code in loops.

Instead of calling the same function three times in a loop, multiply the
loop counter by three.
And since the value in DAC_TEST_PARMS is always the same we can use the
value directly.
