From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Message-ID: <54A7B663.3010507@sunrus.com.cn> Date: Sat, 03 Jan 2015 17:29:07 +0800 From: Chen Gang MIME-Version: 1.0 Subject: [PATCH] s390: boot: compressed: misc: Express the return value of _sclp_print_early() Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-Archive: List-Post: To: schwidefsky@de.ibm.com, heiko.carstens@de.ibm.com Cc: linux-s390@vger.kernel.org, "linux-kernel@vger.kernel.org" List-ID: _sclp_print_early() has return value: at present, return 0 for OK, 1 for failure. It returns '%r2', so use 'long' as return value (upper caller can check '%r2' directly). The related warning: CC arch/s390/boot/compressed/misc.o arch/s390/boot/compressed/misc.c:66:8: warning: type defaults to 'int' in declaration of '_sclp_print_early' [-Wimplicit-int] extern _sclp_print_early(const char *); ^ At present, _sclp_print_early() is only used by puts(), so can still remain its declaration in 'misc.c' file.
