| Subject: dmaengine: idxd: clear block on fault flag when clear wq |
| |
| From: Dave Jiang <dave.jiang@intel.com> |
| |
| [ Upstream commit bd2f4ae5e019efcfadd6b491204fd60adf14f4a3 ] |
| |
| 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. |
| |
