From ece9528e5f88cee11303fceefe39382f1030cd4e Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 12 Jul 2011 08:18:15 -0700 Subject: gpio/omap: replace MOD_REG_BIT macro with static inline This macro is ugly and confusing, especially since it passes in most arguments, but uses an implied 'base' from the caller. Replace it with an equivalent static inline.
