From 9d0f14393ca57bf93ad2a61d802b6265b9f59fe0 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 10 Jul 2012 17:14:25 -0700 Subject: [PATCH] staging: comedi: rtd520: remove RtdDma0Mode macro This macro uses the 'devpriv' macro which relies on a local variable having a specific name. Plus it's just a wrapper around a simple 'writel'. Remove the macro.
