| Subject: dmaengine: at_xdmac: remove a stray bottom half unlock |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| [ Upstream commit 0b515abb6b7eb08e90bdfc01fc8fbdd112c15d81 ] |
| |
| We switched this code from spin_lock_bh() to vanilla spin_lock() but |
| there was one stray spin_unlock_bh() that was overlooked. This |
| patch converts it to spin_unlock() as well. |
| |
| Fixes: d8570d018f69 ("dmaengine: at_xdmac: move spin_lock_bh to spin_lock in tasklet") |
