From: H Hartley Sweeten Date: Fri, 1 May 2015 21:59:02 +0000 (-0700) Subject: staging: comedi: ni_stc.h: tidy up DIO_Control_Register and bits X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=59a97c3c867797c68bf14ce1620ac8a8f695eef0;p=linux-beck.git staging: comedi: ni_stc.h: tidy up DIO_Control_Register and bits Rename the CamelCase. Use the BIT() macro to define the bits.
