From: Ian Abbott Date: Tue, 8 Oct 2013 18:06:22 +0000 (+0100) Subject: staging: comedi: s626: remove I2CR and I2CW macros X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d5512f5b5b58e7ae47045315ade7df8873617992;p=linux-beck.git 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.
