From 59ddbe2697c7c38e652ee7ae06aa79fbbf398107 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1611/4131] drm/amdkfd: Fix error messages about updating wrong
VMID
Don't try to set the page table base for a QPD that doesn't have a
valid VMID. A VMID is only assigned as long as queues exist. So check
if the queue list is empty first.
