[PATCH 5.4 06/90] drm/amdgpu: move kfd suspend after ip_suspend_phase1

From: Greg Kroah-Hartman
Date: Wed May 13 2020 - 06:03:10 EST


From: Evan Quan <evan.quan@xxxxxxx>

[ Upstream commit c457a273e118bb96e1db8d1825f313e6cafe4258 ]

This sequence change should be safe as what did in ip_suspend_phase1
is to suspend DCE only. And this is a prerequisite for coming
redundant cg/pg ungate dropping.

Fixes: 487eca11a321ef ("drm/amdgpu: fix gfx hang during suspend with video playback (v2)")
