From 898fcb98066cfcd6051d61638e7e3a305de34c85 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 21 Feb 2011 10:09:06 +0100 Subject: [PATCH] Staging: xgifb: Remove unused functions Earlier patch removed code that never got executed because it depended on XGIfb_accel variable value to de distinct than 0. But this variable is always 0 in current driver. That dead code used a set of functions that not remains unused. This patch removes these unused functions.
