Subject: Staging: xgifb: Removes dead code
X-Git-Tag: firefly_0821_release~7613^2~2197^2~434
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cfd6ea0b731d048037ba00b8dd3777a91b9675e0;p=firefly-linux-kernel-4.4.55.git

Staging: xgifb: Removes dead code

xgifb staging driver has code that dependens on XGIfb_accel != 0.
But as Dan Carpenter noticed, XGIfb_accel value is always 0 in current driver.
So there is code that never gets executed.

This patch removes this dead code.
