[PATCH 1/3] staging: comedi: amplc_pc263: abbreviate IS_ENABLED()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The IS_ENABLED(CONFIG_COMEDI_AMPLC_PC263_ISA) and
IS_ENABLED(CONFIG_COMEDI_AMPLC_PC263_PCI) macro calls are a bit
long-winded.  Define a couple of macros DO_ISA and DO_PCI as
abbreviations for them.
