From cb6c89a094df3823a1797b880e5dfda2fbfcd584 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 24 Aug 2011 17:28:40 +0100 Subject: [PATCH] staging:iio:trigger core. Trivial code cleanups. Stop exporting functions only intended for core usage. Return void from function which can never return anything other than 0. Trivial stype cleanups.
