From c6c732cf9ff0547430a9dedc3fcf6a93f4db54ab Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 27 May 2013 15:14:40 +0300 Subject: [PATCH] ipu_idmac: re-use dma_cookie_status() It's better to use generic dma_cookie_status() that allows user to get standard possible return codes independently of the DMAC driver in charge.
