Subject[PATCH 5.4 093/102] dmaengine: ti: edma: fix missed failure handling
Date
From: Chuhong Yuan <hslester96@gmail.com>

[ Upstream commit 340049d453682a9fe8d91fe794dd091730f4bb25 ]

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")
