/**

 * 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

 *

 * 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.

 *

 * Same as usb_find_common_endpoints(), but the endpoint descriptors are

 * searched in reverse order (see usb_find_common_endpoints() for details).

 * Return: Zero if all requested descriptors were found, or -ENXIO otherwise.
