Date: Thu, 16 Jan 2020 11:42:22 -0500 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Chuhong Yuan <hslester96@...il.com>, Vinod Koul <vkoul@...nel.org>, Sasha Levin <sashal@...nel.org>, dmaengine@...r.kernel.org Subject: [PATCH AUTOSEL 5.4 167/205] dmaengine: ti: edma: fix missed failure handling From: Chuhong Yuan <hslester96@...il.com> [ Upstream commit 340049d453682a9fe8d91fe794dd091730f4bb25 ] When devm_kcalloc fails, it forgets to call edma_free_slot. Replace direct return with failure handler to fix it.
