The declarations of ssusb_gadget_{init,exit} are in the mtu3_dr.h file but the code does that implements them does not include this. Add the include to fix the following sparse warnigns: drivers/usb/mtu3/mtu3_core.c:825:5: warning: symbol 'ssusb_gadget_init' was not declared. Should it be static? drivers/usb/mtu3/mtu3_core.c:925:6: warning: symbol 'ssusb_gadget_exit' was not declared. Should it be static?
