Subject: [PATCH 5/5] [RESEND] x86: alternative: add __alt_reloc_selftest prototype
Date: Tue, 25 Jul 2023 15:48:37 +0200 [thread overview]
Message-ID: <20230725134837.1534228-6-arnd@kernel.org> (raw)
In-Reply-To: <20230725134837.1534228-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
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.
Fixes: 270a69c4485d ("x86/alternative: Support relocations in alternatives")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
