From: H Hartley Sweeten Date: Tue, 11 Nov 2014 23:55:39 +0000 (-0700) Subject: staging: comedi: dmm32at: rename DMM32AT_CNTRL X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d900a48841091e07d34d26a7cb7b29ce0447752c;p=linux-beck.git staging: comedi: dmm32at: rename DMM32AT_CNTRL For aesthetics, rename this define used for the Miscellaneous Control register. Also, rename the defines for the bits of the register.
