Subject: [PATCH] staging: xgifb: Delete an unnecessary check before the function
 call "XGIfb_search_crt2type"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 26 Jun 2015 21:50:41 +0200

The XGIfb_search_crt2type() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
