From 5370cb347676e0af3d49786e6f1e710bc926d3ca Mon Sep 17 00:00:00 2001

Subject: [PATCH 4699/5725] drm/amdgpu:All UVD instances share one idle_work
handle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All UVD instanses have only one dpm control, so it is better
to share one idle_work handle.
