From 58c2fb647a3cf70a90d7b33a3f2a8396a20a0bc4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 1 Sep 2009 12:02:39 +0100 Subject: [PATCH] drm/i915: Unref old_obj on get_fence_reg() error path Remember to release the local reference if we fail to wait on the rendering. (Also whilst in the vicinity add some whitespace so that the phasing of the operations is clearer.)
