Subject: usb: cdnsp: Fix incorrect supported maximum speed
From: Pawel Laszczak <pawell@xxxxxxxxxxx>
commit aa82f94e869edd72f4fadb08c6ffca8927e4934e upstream.
Driver had hardcoded in initialization maximum supported speed
to USB_SPEED_SUPER_PLUS but it should consider the speed
returned from usb_get_maximum_speed function.
