Subject: staging: comedi: ni_stc.h: tidy up the cs5529_configuration_bits
X-Git-Tag: v4.2-rc1~88^2~657
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b738aa3a131bdc670191318bebc558629b3f1ed4;p=karo-tx-linux.git

staging: comedi: ni_stc.h: tidy up the cs5529_configuration_bits

For aesthetics, convert the enum into defines and the inline functions
into macros. Use the BIT() macro to define the bits.
