In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: invoke pm_genpd_remove() before freeing genpd
Call pm_genpd_remove() to unregister from global list prior to releasing acp_genpd memory, and clear the pointer after free.
(cherry picked from commit cd8650d7a91ee8b768e202354672553faa5cc1f2)
