From 3a4959a3a0bd50bbbc5101abec6420d56582ec98 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 23 Feb 2015 14:57:56 -0700 Subject: [PATCH] staging: comedi: amplc_dio200_common: remove 'clk_sce_ofs' from struct dio200_subdev_8254 This member is only used one place in the driver. Remove it and calculate the register offset when needed.
