Merge tag 'usb-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman:
"Here's the big USB patch set for the 3.6-rc1 merge window.
Lots of little changes in here, primarily for gadget controllers and
drivers. There's some scsi changes that I think also went in through
the scsi tree, but they merge just fine. All of these patches have
been in the linux-next tree for a while now.
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
Fix up trivial conflicts in include/scsi/scsi_device.h (same libata
conflict that Jeff had already encountered)
