From: H Hartley Sweeten Date: Fri, 1 May 2015 21:59:35 +0000 (-0700) Subject: staging: comedi: ni_stc.h: tidy up AO_Output_Control_Register and bits X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5bd1c7283794112234aace1ef679c947d26a841e;p=linux-beck.git staging: comedi: ni_stc.h: tidy up AO_Output_Control_Register and bits Rename the CamelCase. Convert the inline helper function into a macro and use the BIT() marco to define the bits.
