Subject: [34-longterm 158/179] USB: usb-storage: unusual_devs entry for ARM V2M motherboard.

From: Nick Bowler <nbowler@...iptictech.com>

                   -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
    If you see a problem with using this for longterm, please comment.
                   -------------------

commit a871e4f5519d8c52430052e1d340dd5710eb5ad6 upstream.

Connecting the V2M to a Linux host results in a constant stream of
errors spammed to the console, all of the form

  sd 1:0:0:0: ioctl_internal_command return code = 8070000
     : Sense Key : 0x4 [current]
     : ASC=0x0 ASCQ=0x0

The errors appear to be otherwise harmless.  Add an unusual_devs entry
which eliminates all of the error messages.

[PG: 2.6.34 uses US_ prefix, not USB_ prefix, change accordingly]
