[PATCH 12/34] apm-emulation: hide an unused variable

From: Arnd Bergmann
Date: Wed Apr 03 2024 - 04:24:52 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

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")
