From fac9d8850a0c94c1d237fef2a3a238f7dbed39cf Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 26 Sep 2017 20:58:28 +0200 Subject: gpio: Get rid of _prefix and __prefixes The arbitrarily marking of a function with _ or __ is taking to mean "perform some inner core of the caller" or something like that. At other times, this syntax has a totally different meaning. I don't like this since it is unambious and unhelpful to people reading the code, so replace it with _commit() suffixes.
