Just noticed this when I updated my branch and tried to unblank the display on
my Bayley Bay platform.  dmesg says:

[  626.549976] [drm:intel_dp_complete_link_train] *ERROR* failed to update link
training

I already tried reverting the vdd force change, no help there.  Maybe the fast
& wide commit?
