From 5e8db898fd53b7622e21616f0ff27d985d7be758 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Tue, 9 Feb 2016 11:40:08 +0100 Subject: [PATCH] st/mesa: check ureg_create() retval in create_pbo_upload_vs() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This avoids a possible NULL dereference because ureg_create() might return a NULL pointer.
