Subject: drm/amdkfd: Add missing gfx11 MQD manager callbacks
From: Jay Cornwall <jay.cornwall@xxxxxxx>
commit e9dca969b2426702a73719ab9207e43c6d80b581 upstream.
mqd_stride function was introduced in commit 2f77b9a242a2
("drm/amdkfd: Update MQD management on multi XCC setup")
but not assigned for gfx11. Fixes a NULL dereference in debugfs.
