From ca22e3cc25f180859561f36d51bf21278db5ae11 Mon Sep 17 00:00:00 2001 From: Seung-Woo Kim Date: Tue, 15 Nov 2011 16:25:39 +0900 Subject: [PATCH] drm/exynos: fixed wrong err ptr usage and destroy call in exeception - exynos_drm_buf_create() returns err pointer so NULL check is wrong. - Case that exynos_gem_obj is not created, destroy call in exception handle lable uses this pointer. so instead buffer is directly used.
