3.16.7-ckt5 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
commit 7f5c4d631aed243ca89c6673427954210b1628ec upstream.
Streams do not work reliabe on Fresco Logic FL1000G xhci controllers, trying to use them results in errors like this:
21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled endpoint or incorrect stream ring 21:37:33 kernel: xhci_hcd 0000:04:00.0: @00000000368b3570 9067b000 00000000 05000000 01078001 21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled endpoint or incorrect stream ring 21:37:33 kernel: xhci_hcd 0000:04:00.0: @00000000368b3580 9067b400 00000000 05000000 01038001
As always I've ordered a pci-e addon card with a Fresco Logic controller for myself to see if I can come up with a better fix then the big hammer, in the mean time this will make uas devices work again (in usb-storage mode) for FL1000G users.
