From 155ce496031888e7d1388c755775233544644eec Mon Sep 17 00:00:00 2001 From: Nicolai Hähnle Date: Fri, 29 Apr 2016 16:18:27 -0500 Subject: radeonsi: fix PIPE_FORMAT_R11G11B10_FLOAT handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit That format has first_non_void < 0. This fixes a regression in piglit arb_shader_image_load_store-semantics that was introduced by commit 76b8c5cc602, while hopefully still shutting Coverity up (and failing in a more obvious way if a similar error should re-appear).
