Subject: staging/xgifb: Remove uneccessary/simply if in XGINew_GetXG20DRAMType
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fb70b191ee8fc29264791b0c25ec2925b98bb0e3;p=linux-beck.git

staging/xgifb: Remove uneccessary/simply if in XGINew_GetXG20DRAMType

Instead of storing the value in a temp variable, anding it with 1 and
assign data conditionally we can assign the value directly.
