== Precise SRU Justification ==

This bug is preventing users from using some usb 3.0 HD.(hitachi/LaCie/...)
at UAS mode.

== Fix ==
Both the patches have been in upstream 3.3:

e4d8318 usb/uas: make sure data urb is gone if we receive status before that
ee398b5 usb/uas: add usb_pipe_usage_descriptor
348748b usb/uas: move UAS structs / defines into a header file
c898add usb/uas: only bind if the hcd supports SG
ceb3f91 usb/uas: one only one status URB/host on stream-less connection
22188f4 usb/uas: use scsi_host_find_tag() to find command from a tag
dae5154 usb/uas: use unique tags for all LUNs
96c1eb9 UAS: Free status URB when we can't find the SCSI tag.
9eb4454 UAS: Use unique tags on non-streams devices.
ea9da1c UAS: Re-add workqueue items if submission fails.
