Subject: xhci: Treat not finding the event_seg on COMP_STOP the same as COMP_STOP_INVAL
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit 9a54886342e227433aebc9d374f8ae268a836475 upstream.
When using a Renesas uPD720231 chipset usb-3 uas to sata bridge with a 120G
Crucial M500 ssd, model string: Crucial_ CT120M500SSD1, together with a
the integrated Intel xhci controller on a Haswell laptop:
00:14.0 USB controller [0c03]: Intel Corporation 8 Series USB xHCI HC [8086:9c31] (rev 04)
The following error gets logged to dmesg:
xhci error: Transfer event TRB DMA ptr not part of current TD
Treating COMP_STOP the same as COMP_STOP_INVAL when no event_seg gets found
fixes this.
