0001-usb-xhci-do-not-perform-Soft-Retry-for-some-xHCI-hos.patch

This is next proposed fix. It suppose to disable Soft Retry for affected xHCI controllers. Currently only for xHCI device reported by Michael:
PCI_VENDOR_ID_AMD = 0x1022 , PCI_DEVICE_ID_AMD_PROMONTORYA_4 = 0x43b9

If you want to test and have different xHCI host you need to add your PCI-id's to
drivers/usb/host/xhci-pci.c part of the patch.
