| |
In the iforce driver we currently get this warning
drivers/input/joystick/iforce/iforce-packets.c: In function 'iforce_get_id_packet': drivers/input/joystick/iforce/iforce-packets.c:249: warning: unused variable 'status'
if CONFIG_JOYSTICK_IFORCE_USB is not defined.
The warning is easy to avoid by simply moving the variable inside the only case in the switch that actually use it.
