Subject: [PATCH] ARM: b.L: fix unmet dependency for CPU_PM
Date: Thu, 13 Nov 2014 11:08:18 +0530
Message-id: <1415857098-16928-1-git-send-email-pankaj.dubey@samsung.com>

Sender: linux-kernel-owner@vger.kernel.org

If BL_SWITCHER is enabled but SUSPEND and CPU_IDLE is not enabled
we are getting following config warning.

warning: (BL_SWITCHER) selects CPU_PM which has unmet direct
dependencies (SUSPEND || CPU_IDLE)

So BL_SWITCHER should enable CPU_PM only if either of SUSPEND or
CPU_IDLE is selected.
