Subject: [PATCH] drivers: usb: Mark function as static in metro-usb.c
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Mark function metrousb_is_unidirectional_mode() in serial/metro-usb.c
because it is not used outside this file.

This eliminates the following warning in serial/metro-usb.c:
drivers/usb/serial/metro-usb.c:57:12: warning: no previous prototype for ‘metrousb_is_unidirectional_mode’ [-Wmissing-prototypes]
