From 03187c72db60e20354aca6802bc5cc3e42c1d6e1 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 8 Jun 2014 22:47:10 +0800 Subject: regulator: ab8500: Remove ab8500_regulator_debug_init/exit() CONFIG_REGULATOR_AB8500_DEBUG is always not defined. ab8500_regulator_debug_init() is not called at all now, ab8500_regulator_debug_exit() simply return 0, thus remove them.
