Merge tag 'for-usb-next-2012-05-18' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next
xhci: Link PM and bug fixes for 3.5. Hi Greg, Here's the final Link Power Management patches, along with a couple of bug fixes that have been sitting in my queue. I've fixed all the comments that Alan and Andiry had on the Link PM patches, so I think they're ready to go. Sarah Sharp
