NAME

       usb_gstrings_attach - attach gadget strings to a cdev and assign ids

SYNOPSIS

       struct usb_string * usb_gstrings_attach(struct usb_composite_dev * cdev, struct usb_gadget_strings ** sp, unsigned n_strings);

ARGUMENTS

       cdev
	   the device whose string descriptor IDs are being allocated and attached.

       sp
	   an array of usb_gadget_strings to attach.

       n_strings
	   number of entries in each usb_strings array (sp[]->strings)

DESCRIPTION

       This function will create a deep copy of usb_gadget_strings and usb_string and attach it to the cdev. The actual string (usb_string.s) will
       not be copied but only a referenced will be made. The struct usb_gadget_strings array may contain multiple languges and should be NULL
       terminated. The ->language pointer of each struct usb_gadget_strings has to contain the same amount of entries.

FOR INSTANCE

       sp[0] is en-US, sp[1] is es-ES. It is expected that the first usb_string entry of es-ES containts the translation of the first usb_string
       entry of en-US. Therefore both entries become the same id assign.
