From 6b676e66343356d5096260c2bc1601014c808cb0 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Wed, 26 Jun 2013 13:53:15 -0700 Subject: [PATCH] i965,i915: Return early if miptree allocation fails If allocation fails in intel_miptree_create_layout(), don't proceed to dereference the miptree. Return an early NULL. Fixes static analysis error reported by Klocwork. Note: This is a candidate for the 9.1 branch.
