3.2.51-rc1 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>
[bwh: Backported to 3.2: adjust context, drop changes to cik.c and si.c]
