From 8a46f4f7f95f2bece108998a2e1b87b58f99d590 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 1 Jun 2013 00:22:52 +0200 Subject: of: remove #ifdef from linux/of_platform.h A lot of code uses the functions from of_platform.h when built for devicetree-enabled platforms but can also be built without them. In order to avoid using #ifdef everywhere in drivers, this makes all the function declarations visible, which means we can use "if (IS_ENABLED(CONFIG_OF))" in driver code and get build coverage over the code but let the compiler drop the reference in the object code.
