Summary

drm/msm/gpu: Fix crash when throttling GPU immediately during boot

Original description

The description as published by the source.

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

drm/msm/gpu: Fix crash when throttling GPU immediately during boot

There is a small chance that the GPU is already hot during boot. In that
case, the call to of_devfreq_cooling_register() will immediately try to
apply devfreq cooling, as seen in the following crash:

At this point we haven't initialized the GMU at all yet, so…
