drm/radeon: always program the MC on startup
commit 6fab3febf6d949b0a12b1e4e73db38e4a177a79e upstream. 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. Based on a fix from: Mark Kettenis <kettenis@openbsd.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> [ rebased for 3.10 and dropped the drivers/gpu/drm/radeon/cik.c bit as it's 3.11 specific code / tmb ] Signed-off-by: Thomas Backlund <tmb@mageia.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
