USB function's configfs config group is created in a generic way in usb/gadget/configfs.c:function_make(), which in turn delegates actual allocation and setup of the USB function instance to a particular implementation, e.g. in f_acm.c. The said implementation does its job in a parameter-less function e.g. acm_alloc_instance(), which results in creating an unnamed config group, whose name is set later in function_make(). function_make() creates the name by parsing a string of the form: <function name>.<instance name> which comes from userspace as a parameter to mkdir invocation. Up to now only <function name> has been used, while <instance name> has been ignored. This patch adds a set_inst_name() operation to struct usb_function_instance which allows passing the <instance name> from function_make() so that it is not ignored. It is entirely up to the implementor of set_inst_name() what to do with the <instance name>. In a typical case, the struct usb_function_instance is embedded in a larger struct which is retrieved in set_inst_name() with container_of(), and the larger struct contains a field to store the <instance name>.
