From 12e45e89556d7a532120f976081e9e7582addd2b Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Tue, 5 Apr 2022 14:53:39 -0700 Subject: [PATCH] dmaengine: idxd: fix device cleanup on disable There are certain parts of WQ that needs to be cleaned up even after WQ is disabled during the device disable. Those are the unchangeable parts for a WQ when the device is still enabled. Move the cleanup outside of WQ state check. Remove idxd_wq_disable_cleanup() inside idxd_wq_device_reset_cleanup() since only the unchangeable parts need to be cleared.
