In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm/si: Don't schedule thermal work when queue isn't initialized
When DPM is turned off with the amdgpu.dpm=0 module parameter,
the thermal work queue isn't initialized so we shouldn't
schedule any work on it.
(cherry picked from commit bd018d36171a695952c6d391471c279c9e05c8b2)
