Subject: [PATCH] xen: xen_debug_interrupt prototype to global header
Date: Wed, 17 May 2023 14:45:07 +0200 [thread overview]
Message-ID: <20230517124525.929201-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The xen_debug_interrupt() function is only called on x86, which has a
prototype in an architecture specific header, but the definition also
exists on others, where the lack of a prototype causes a W=1 warning:
drivers/xen/events/events_2l.c:264:13: error: no previous prototype for 'xen_debug_interrupt' [-Werror=missing-prototypes]
Move the prototype into a global header instead to avoid this warning.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
