From a6eaa2ae7820f0cca742917f85f34ef1eed2c95d Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 2 Sep 2013 23:37:53 -0300 Subject: [PATCH] of_mtd: Add no-op stubs to support CONFIG_OF=n Just like the rest of the subsystems, let's add the required no-op functions to implement stubs when CONFIG_OF=n. This prevents MTD drivers from having ugly ifdefs in their code, and instead hide the ifdef monster in the header closet (far away from people's sight).
