From 3ab4ca10d298bfd425afbd8487538fafa9b77a13 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 3 Sep 2014 13:45:45 +0100 Subject: [PATCH] staging: comedi: add CMDF_ROUND_... as synonyms for TRIG_ROUND_... The `TRIG_ROUND_...` macros are some of the values that can be OR-ed into the `flags` member of `struct comedi_cmd`. They may influence the rounding of sample timings during operation of the asynchronous command. The names are a bit of a left-over from earlier times. It would be better to use the names `CMDF_ROUND_...` to match various other command flags. Define `CMDF_ROUND_MASK`, `CMDF_ROUND_NEAREST`, `CMDF_ROUND_DOWN`, `CMDF_ROUND_UP` and `CMDF_ROUND_UP_NEXT` with the same numeric values as `TRIG_ROUND_MASK`, `TRIG_ROUND_NEAREST`, `TRIG_ROUND_DOWN`, `TRIG_ROUND_UP` and `TRIG_ROUND_UP_NEXT`, and redefine the `TRIG_ROUND_...` macros as synonyms of the `CMDF_ROUND_...` macros.
