[PATCH] drm: stop vmgfx driver explosion

2012-08-20 Thread Alan Cox
From: Alan Cox If you do a page flip with no flags set then event is NULL. If event is NULL then the vmw_gfx driver likes to go digging into NULL and extracts NULL->base.file_priv. On a modern kernel with NULL mapping protection it's just another oops, without it there are some "intriguing" poss
