Vulnerability from github
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.
