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

drm/amdgpu: fix GEM object leak on ENOMEM in userptr ioctl

When amdgpu_hmm_range_alloc() fails amdgpu_gem_userptr_ioctl() returns
-ENOMEM right away and skips the cleanup every other error path goes
through. The GEM object, the bo->parent reference on the VM root and the
MMU notifier registration are all left behind.

Use release_object here, not user_pages_done, range is still NULL at
this point.

(cherry picked from commit bbe739e407a542073ec1a7872b14843566b4919e)
