From b26072276f20ce93717fdad5210e4ae9f1c944fa Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Tue, 10 Mar 2015 11:37:24 +0200 Subject: dmaengine: dw: Make error prints unique. Part #2 The same error message is printed from different switch cases. Since both of these jump into same error label we can move error print there and add a DMA direction in order to make it easier to grep error from sources.
