void usb_serial_deregister_drivers

(

struct usb_serial_driver *const

)

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().
