From 0231e470b3dff703333c4a7cc94c240c9b4eb197 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1270/2940] drm/amdgpu: Set DPM_FLAG_NEVER_SKIP when enabling
PM-runtime
Based on a similar patch from Rafael for radeon.
When using ATPX to control dGPU power, the state is not retained
across suspend and resume cycles by default. This can probably
be loosened for Hybrid Graphics (_PR3) laptops where I think the
state is properly retained.
Fixes: c62ec4610c40 ("PM / core: Fix direct_complete handling for devices with no callbacks")
