Subject: staging/xgifb: Remove code without effect
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=516354e0b458c3c16555364e105bdee5cd1cf5f1;p=deliverable%2Flinux.git

staging/xgifb: Remove code without effect

The tempal variable is assigned and then immediately overwritten.
-> remove everything without effect.

The inb is kept for possible side effects.
