If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From a8a04c994d41a489eb0f2899893209e04e030153 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@xxxxxxx> Date: Wed, 27 Jul 2016 15:31:59 -0400 Subject: drm/amdgpu: fix firmware info version checks From: Alex Deucher <alexander.deucher@xxxxxxx> commit a8a04c994d41a489eb0f2899893209e04e030153 upstream. Some of the checks didn't handle frev 2 tables properly. amdgpu doesn't support any tables pre-frev 2, so drop the checks.
