    usb: gadget: rndis: remove the limit of available rndis connections · d6d22922

    RNDIS function has a limitation on the number of allowed instances.
    So far it has been RNDIS_MAX_CONFIGS, which happens to be one.
    In order to eliminate this kind of arbitrary limitation we should not
    preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params
    instances but instead allow allocating them on demand.
    
    This patch allocates struct rndis_params on demand in rndis_register().
    Coversly, the structure is free()'d in rndis_deregister().
    If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which
    is the same behaviour as before, but the moment of creation is delayed
    until struct rndis_params is actually allocated.
    
    rnids_init() and rndis_exit() have nothing to do, so they are eliminated.
