From 153012b29b4f2183a1be6a01eec63e720a192718 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Sat, 11 Apr 2009 14:02:33 -0700 Subject: [PATCH] DRI2: Don't fault on NULL DrawBuffer It is possible for ctx->DrawBuffer to be NULL, so don't fault when that happens. This change is not being committed to master because it doesn't appear to be necessary there.
