Btw, xhci-ring.c causes some valid looking gcc warnings:

C [M]  drivers/usb/host/xhci-ring.o
drivers/usb/host/xhci-ring.c: In function âhandle_port_statusâ:
drivers/usb/host/xhci-ring.c:1229: warning: âhcdâ may be used uninitialized in this function
drivers/usb/host/xhci-ring.c: In function âhandle_tx_eventâ:
drivers/usb/host/xhci-ring.c:1895: warning: âevent_trbâ may be used uninitialized in this function

regards,
