From 4c91930a257ac500029f56514c5504ad66b7cf8f Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 21 Aug 2013 13:20:05 -0400 Subject: freedreno: fix segfault when no color buffer bound Don't crash when no color buffer bound. Something caught when starting to run piglit, fixes a hanful of piglit tests.
