From 3c9b7733958fb861c3df7d56481c8e97613088d3 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 12 Oct 2015 11:01:34 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: tidy up PCI1720_* register defines The PCI-1720 board is supported by this driver but uses a different register map. For aesthetics, rename the defines to match the PCI171X_* format.
