From: Arnd Bergmann Date: Thu, 3 Aug 2023 08:26:17 +0000 (+0200) Subject: x86/alternative: Add a __alt_reloc_selftest() prototype X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a3e4b4da39bbf540a379e21869faa74bb19d16f;p=linux.git x86/alternative: Add a __alt_reloc_selftest() prototype The newly introduced selftest function causes a warning when -Wmissing-prototypes is enabled: arch/x86/kernel/alternative.c:1461:32: error: no previous prototype for '__alt_reloc_selftest' [-Werror=missing-prototypes] Since it's only used locally, add the prototype directly in front of it.
