From 275cc0c8bd3c0a6b826d46a4d1a8135897387ca9 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 15 Nov 2012 15:09:42 +0100 Subject: [PATCH] dma: mv_xor: use mv_xor_chan pointers as arguments to self-test functions In preparation for the removal of the mv_xor_device structure, we directly pass mv_xor_chan pointers to the self-test functions included in the driver. These functions were anyway selecting the first (and only channel) available in each DMA device, so the behaviour is unchanged.
