xhci: Disable streams on Via XHCI with device-id 0x3432
This is a bit bigger hammer then I would like to use for this, but for now it will have to make do. I'm working on getting my hands on one of these so that I can try to get streams to work (with a quirk flag if necessary) and then we can re-enable them. For now this at least makes uas capable disk enclosures work again by forcing fallback to the usb-storage driver. https://bugzilla.kernel.org/show_bug.cgi?id=79511 Cc: stable@vger.kernel.org # 3.15 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
