From d5512f5b5b58e7ae47045315ade7df8873617992 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 8 Oct 2013 19:06:22 +0100 Subject: [PATCH] staging: comedi: s626: remove I2CR and I2CW macros The `I2CR` and `I2CW` macros expand to the I2C read and write addresses, respectively. They are only used in one place each and include the name of a local variable `devpriv` in their expansion. Get rid of the macros and expand them in place.
