1602 * We need to differentiate between the surprise and planned removal of the
1603 * device because of the following consideration:
1604 *
1605 * - In case of surprise removal, the hcd already frees up the pending
1606 * for the device and hence there is no need to unregister the function
1607 * driver inorder to get these requests. For planned removal, the function
1608 * driver has to explicitly unregister itself to have the hcd return all the
1609 * pending requests before the data structures for the devices are freed up.
1610 * Note that as per the current implementation, the function driver will
1611 * end up releasing all the devices since there is no API to selectively
1612 * release a particular device.
1613 *
1614 * - Certain commands issued to the target can be skipped for surprise
1615 * removal since they will anyway not go through.
