CVE-2022-50527

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix size validation for non-exclusive domains (v4)
Fix amdgpu_bo_validate_size() to check whether the TTM domain manager for the requested memory exists, else we get a kernel oops when dereferencing "man".
v2: Make the patch standalone, i.e. not dependent on local patches. v3: Preserve old behaviour and just check that the manager pointer is not NULL. v4: Complain if GTT domain requested and it is uninitialized–most likely a bug.
