[PATCH 5.13 154/175] usb: cdnsp: Fix incorrect supported maximum speed

From: Greg Kroah-Hartman
Date: Tue Aug 10 2021 - 14:06:30 EST


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.
