3.5.7.19 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
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@xxxxxxxxxxx>
Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx>
[ luis: backported to 3.5:
- adjusted context
- dropped changes to drivers/gpu/drm/radeon/cik.c ]
