From 2157f896774ace6e98c851878f8089fb861502e2 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Thu, 9 Feb 2012 14:24:41 -0800 Subject: [PATCH] staging: android-alarm: Support old drivers via preprocessor aliasing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Older out of tree drivers that were desgined to the Android Alarm in-kernel API may not build due to the namespace collision fixed in an earlier patch. Per Arve's suggestion, this patch provides preprocessor macros that allow older drivers to build.
