ALSA: line6: Use correct endpoint type for midi output
Sending MIDI messages to a PODxt through the USB connection shows "usb_submit_urb failed" in dmesg and the message is not received by the POD. The error is caused because in the funcion send_midi_async() in midi.c there is a call to usb_sndbulkpipe() for endpoint 3 OUT, but the PODxt USB descriptor shows that this endpoint it's an interrupt endpoint. Patch tested with PODxt only. [ The bug has been present from the very beginning in the staging driver time, but Fixes below points to the commit moving to sound/ directory so that the fix can be cleanly applied -- tiwai ] Fixes: 61864d844c29 ("ALSA: move line6 usb driver into sound/usb") Signed-off-by: Fabián Inostroza <fabianinostroza@udec.cl> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
