From 44e1312c68e71a25f9f88ada7d124f5bbeaf879e Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Sun, 3 Feb 2013 22:54:31 +0100 Subject: [PATCH] staging/xgifb: Remove always false comparisons This patch removes some comparisons that always evaluate to false since xoffset and yoffset are defined as __u32 in fb_var_screeninfo in include/linux/fb.h and thus can never be negative.
