/**
|

* 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.
