Subject: [PATCH] dmaengine: idxd: clear block on fault flag when clear wq
Git-commit: bd2f4ae5e019efcfadd6b491204fd60adf14f4a3
Patch-mainline: v5.15-rc1
References: git-fixes stable-5.14.8

The block on fault flag is not cleared when we disable or reset wq. This
causes it to remain set if the user does not clear it on the next
configuration load. Add clear of flag in dxd_wq_disable_cleanup()
routine.
