void usb_serial_deregister_drivers ( struct usb_serial_driver *const  serial_drivers[])

usb_serial_deregister_drivers - deregister drivers for a usb-serial module : NULL-terminated array of pointers to drivers to be deregistered

Deregisters all the drivers in the array and deregisters and frees the struct usb_driver that was created by the call to usb_serial_register_drivers().

usb_serial_generic_write - generic write function for serial USB devices : Pointer to &struct tty_struct for the device : Pointer to the &usb_serial_port structure for the device : Pointer to the data to write : Number of bytes to write

Returns the number of characters actually written, which may be anything from zero to . If an error occurs, it returns the negative errno value.
