Take DECLARE_USB_FUNCTION_INIT(ffs, ffs_alloc_inst, ffs_alloc) as example, it will generate function ffsmod_init/ffsmod_exit() and variable ffsusb_func. Add possible character '_' in the macro which will generate function/variable name in common format, ffs_mod_init/ffs_mod_exit() and ffs_usb_func. It will apply to all gadget functions which use this macro.
