Merge tag 'for-usb-linus-2012-08-08' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-linus
xHCI bug fixes and host quirks.
Hi Greg,
Here's four patches for 3.6. Most are marked for stable as well.
The first one makes the xHCI driver load properly on newer Rensas hosts.
The next two fix issues with the Etron host incorrectly marking short
transfers as successful, and avoiding log warning spam for hosts that
make the same mistake.
The last patch fixes a really nasty xHCI driver bug that could cause
general protection faults when devices stall transfers.
Sarah Sharp
