NAME
       usb_add_function - add a function to a configuration

SYNOPSIS
       int usb_add_function(struct usb_configuration * config, struct usb_function * function);

ARGUMENTS
       config
           the configuration

       function
           the function being added

CONTEXT
       single threaded during gadget setup

DESCRIPTION
       After initialization, each configuration must have one or more functions added to it.
       Adding a function involves calling its bind() method to allocate resources such as
       interface and string identifiers and endpoints.

       This function returns the value of the function's bind, which is zero for success else a
       negative errno value.
