Subject[PATCH 5.17 033/343] drm/amdgpu: Fix an error message in rmmod
Date
From: Tianci.Yin <tianci.yin@amd.com>

[ Upstream commit 7270e8957eb9aacf5914605d04865f3829a14bce ]

[why]
In rmmod procedure, kfd sends cp a dequeue request, but the
request does not get response, then an error message "cp
queue pipe 4 queue 0 preemption failed" printed.

[how]
Performing kfd suspending after disabling gfxoff can fix it.
