From 58f1fde22e3d1faffcc8d0e5b5fa62bd9d9ee5d4 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 10 Jul 2012 17:09:31 -0700 Subject: [PATCH] staging: comedi: rtd520: remove RtdDacUpdate 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 'writew'. Remove the macro.
