From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Mathieu Malaterre Subject: [PATCH] powerpc/power: Expose pfn_is_nosave prototype Date: Thu, 23 May 2019 13:47:36 +0200 Message-Id: <20190523114736.30268-1-malat@debian.org> MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org List-ID: To: Michael Ellerman Cc: Mathieu Malaterre , Benjamin Herrenschmidt , Paul Mackerras , "Rafael J. Wysocki" , Len Brown , Pavel Machek , linuxppc-dev@lists.ozlabs.org, linux-kernel@vger.kernel.org, linux-pm@vger.kernel.org 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 in powerpc.
