From 2ead74888a70481aa40b5b6ede42279e1917e66c Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sun, 15 Feb 2015 18:12:06 +0100 Subject: radeonsi: fix a crash if a stencil ref state is set before a DSA state + minor indentation fixes Discovered by Axel Davy. This can't be reproduced with any app, because all state trackers set a DSA state first.
