Subject: [PATCH 09/10] [RESEND 2] apm-emulation: hide an unused variable
Date: Wed, 9 Apr 2025 14:23:01 +0200 [thread overview]
Message-ID: <20250409122314.2848028-9-arnd@kernel.org> (raw)
In-Reply-To: <20250409122314.2848028-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
The driver_version variable is only used inside of an #ifdef block, which
leads to a W=1 warning:
drivers/char/apm-emulation.c:144:19: error: 'driver_version' defined but not used [-Werror=unused-const-variable=]
Move this into the function using it.
Fixes: 7726942fb15e ("[APM] Add shared version of APM emulation")
Acked-by: Jiri Kosina <jkosina@suse.com>
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
