Subject: [PATCH 10/83] staging: comedi: rtd520: remove RtdPacerStartSource macro
Date: Tue, 10 Jul 2012 16:45:22 -0700	[thread overview]
Message-ID: <201207101645.22880.hartleys@visionengravers.com> (raw)

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.
