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