Subject: [PATCH] dmaengine: ti: edma: fix missed failure handling
Git-commit: 340049d453682a9fe8d91fe794dd091730f4bb25
Patch-mainline: v5.5-rc1
References: git-fixes

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")
