| Subject: dmaengine: Revert "dmaengine: shdma: Fix runtime PM imbalance on error" |
| |
| From: Vinod Koul <vkoul@kernel.org> |
| |
| commit d143f939a95696d38ff800ada14402fa50ebbd6c upstream. |
| |
| This reverts commit 455896c53d5b ("dmaengine: shdma: Fix runtime PM |
| imbalance on error") as the patch wrongly reduced the count on error and |
| did not bail out. So drop the count by reverting the patch . |
