From 036b74a7f8adc745c7af089129f070b8e5b8f4bd Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 29 Jun 2011 11:09:49 -0700 Subject: [PATCH] intel: Allow intel_region_reference() with *dst != NULL. This should help us avoid leaking regions in region reference code by making the API more predictable.
