Thanks for the suggestion Stan, unfortunately that one didn't change any
behavior for me, and it appears it is already committed to the 4.19 branch.

I've tested with a custom build direct from 4.19 as well as custom fedora build
from 4.19, and latest fedora release 4.19.13-300.fc29.x86_64, all of which
appear to already have that patch.

Looks like there are a lot of big changes in the two files that seem most
likely culprits to the errors...

$ git diff v4.20 v4.19 -- drivers/gpu/drm/i915/intel_dp_link_training.c | grep
@@ | wc -l
5
$ git diff v4.20 v4.19 -- drivers/gpu/drm/i915/intel_ddi.c | grep @@ | wc -l
16

I'll try to find some time to actually debug the error on v4.19 and find out
what changes resolve the problem, but it may be a while.
