## Overview

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

drm/amdgpu: avoid force-completing uninitialized UVD rings

uvd_v7_0_sw_init() does not initialize the UVD decode ring for an
SR-IOV VF. However, amdgpu_uvd_resume() unconditionally force-completes
the decode ring when restoring its fence sequence.

Skip fence completion when the fence driver is not initialized.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
