From 47de9adece49f78c6e4065bedc69ce13272bc120 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 31 May 2010 19:24:50 +1000 Subject: [PATCH] gallium: fix TFP on gallium This fixes an uninitialised value use in the dri2 st when doing TFP. It uses the driContextPriv which isn't initialised at alloc time.
