[PATCH 4.9 55/69] drm/nouveau/disp/mcp7x: disable dptmds workaround

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Skeggs <bskeggs@xxxxxxxxxx>

commit 7dfee6827780d4228148263545af936d0cae8930 upstream.

The workaround appears to cause regressions on these boards, and from
inspection of RM traces, NVIDIA don't appear to do it on them either.
