resuming from a power state without hotplug support, until the
subsequent EDID based detection.

This patchset fixes a known issue where the DPCD probe quirk leads to
link training failures (patch 1) and limits the quirk to the monitor
which requires it, to avoid similar failures in the future.

Hi,
thanks for following up on this.
You could've added some detail about what the patchset is doing.

drm_dp_dpcd_write_data() can be used to write the GUID for a non-root
MST branch device, similarly to writing the GUID to a root MST branch
device, do so.
