From 10cd04a84bcb6313903fc23b2d7791658ebc6b8e Mon Sep 17 00:00:00 2001 From: Li Peng Date: Sat, 20 Mar 2010 00:21:48 +0800 Subject: [PATCH] Initialize flip_count before using it Otherwise it would be a random value and drmmode_page_flip_handler() won't have a chance to call I830DRI2FlipEventHandler() and indicate a full page flip is complete.
