From 9a23fe65cf36efc6cb40e96405a3f142c7732805 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Tue, 12 Mar 2013 09:27:55 +0000 Subject: [PATCH] cpuidle / kirkwood: remove redundant Kconfig option When the CPU_IDLE and the ARCH_KIRKWOOD options are set it is pointless to define a new option CPU_IDLE_KIRKWOOD because it is redundant. The Makefile drivers directory contains a condition to compile the cpuidle drivers: obj-$(CONFIG_CPU_IDLE) += cpuidle/ Hence, if CPU_IDLE is not set we won't enter this directory. This patch removes the useless Kconfig option and replaces the condition in the Makefile by CONFIG_ARCH_KIRKWOOD. Signed-off-by: Daniel Lezcano Acked-by: Jason Cooper Signed-off-by: Rafael J.
