In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: fix svm_migrate_fini warning Device manager releases
device-specific resources when a driver disconnects from a device,
devm_memunmap_pages and devm_release_mem_region calls in svm_migrate_fini
are redundant. It causes below warning trace after patch “drm/amdgpu: Split
amdgpu_device_fini into early and late”, so remove function
svm_migrate_fini. BUG: https://gitlab.freedesktop.org/drm/amd/-/issues/1718
