Subject: [PATCH] irq_work: consolidate arch_irq_work_raise prototypes
Date: Tue, 16 May 2023 22:02:31 +0200 [thread overview]
Message-ID: <20230516200341.553413-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The prototype was hidden on x86, which causes a warning:
kernel/irq_work.c:72:13: error: no previous prototype for 'arch_irq_work_raise' [-Werror=missing-prototypes]
Fix this by providing it in only one place that is always visible.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
