From 6fab3febf6d949b0a12b1e4e73db38e4a177a79e Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Sun, 4 Aug 2013 12:13:17 -0400 Subject: drm/radeon: always program the MC on startup For r6xx+ asics. This mirrors the behavior of pre-r6xx asics. We need to program the MC even if something else in startup() fails. Failure to do so results in an unusable GPU.
