From 732941ad7f93700f79371bfdf8ec1c521a7c7d54 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Tue, 10 Jul 2012 16:52:45 -0700 Subject: [PATCH] staging: comedi: rtd520: remove RtdInterruptStatus 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 'readw'. Remove the macro.
