From 1ec0cd8286f35988134e05367ab5e66213b84e7c Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Fri, 24 May 2019 12:44:18 +0200 Subject: PM: hibernate: powerpc: Expose pfn_is_nosave() prototype The declaration for pfn_is_nosave is only available in kernel/power/power.h. Since this function can be override in arch, expose it globally. Having a prototype will make sure to avoid warning (sometime treated as error with W=1) such as: arch/powerpc/kernel/suspend.c:18:5: error: no previous prototype for 'pfn_is_nosave' [-Werror=missing-prototypes] This moves the declaration into a globally visible header file and add missing include to avoid a warning on powerpc. Also remove the duplicated prototypes since not required anymore. Signed-off-by: Mathieu Malaterre Acked-by: Michael Ellerman (powerpc) Signed-off-by: Rafael J.
