/**
* usb_find_common_endpoints_reverse() -- look up common endpoint descriptors
* @alt: alternate setting to search
* @bulk_in: pointer to descriptor pointer, or NULL
* @bulk_out: pointer to descriptor pointer, or NULL
* @int_in: pointer to descriptor pointer, or NULL
* @int_out: pointer to descriptor pointer, or NULL
*
* Same as usb_find_common_endpoints(), but the endpoint descriptors are
* searched in reverse order (see usb_find_common_endpoints() for details).
* Search the alternate setting's endpoint descriptors for the last bulk-in,
* bulk-out, interrupt-in and interrupt-out endpoints and return them in the
* provided pointers (unless they are NULL).
*
* If a requested endpoint is not found, the corresponding pointer is set to
* NULL.
*
* Return: Zero if all requested descriptors were found, or -ENXIO otherwise.
