From 0255200bd29afc320c6ea4c1adf8bdc13a9b3c15 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Mon, 29 Oct 2018 12:08:08 +0200 Subject: [PATCH] dmaengine: dmatest: unmap data on a single code-path when xfer done After the DMA transfer is done, we don't need to call the un-mapping code in 3 places. One is enough.
