[ALSA] usb-audio - allow USB MIDI quirks to specify endpoints explicitly
USB generic driver This patch reintroduces the check for endpoint numbers that are specified explicitly in the quirk structure. This check was accidentally dropped in the last rewrite of snd_usbmidi_detect_endpoints(). Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
