From ca4c17f2106e2d1296d335d39ecb2e3d8a9ccccf Mon Sep 17 00:00:00 2001 From: Chuhong Yuan Date: Mon, 18 Nov 2019 15:38:02 +0800 Subject: [PATCH] dmaengine: ti: edma: fix missed failure handling [ Upstream commit 340049d453682a9fe8d91fe794dd091730f4bb25 ] When devm_kcalloc fails, it forgets to call edma_free_slot. Replace direct return with failure handler to fix it.
