From d091bc0a700faabf84eefedea1e133441ad52004 Mon Sep 17 00:00:00 2001 From: Oak Zeng Date: Fri, 14 Jun 2019 19:39:55 -0500 Subject: [PATCH] Revert "drm/amdkfd: Fix a circular lock dependency" This reverts commit 06b89b38f3cc518a761164f9f958a9607bbb3587. This fix is not proper. allocate_mqd can't be moved before allocate_sdma_queue as it depends on q->properties->sdma_id set in later.
