Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix system hang while resume with TBT monitor

[Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume.

The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL.

It will mess up the pipe topology after resume.

[How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default.

(cherry picked from commit 453f86a26945207a16b8f66aaed5962dc2b95b85)
