| Subject: [PATCH] dmaengine: ti: edma: fix missed failure handling |
| |
| commit 340049d453682a9fe8d91fe794dd091730f4bb25 upstream. |
| |
| When devm_kcalloc fails, it forgets to call edma_free_slot. |
| Replace direct return with failure handler to fix it. |
| |
| Fixes: 1be5336bc7ba ("dmaengine: edma: New device tree binding") |
