sound: seq_midi: do not send MIDI reset when closing
Sending a MIDI reset message when closing a port is wrong because we only want to shut the device up, not to reset all settings. Furthermore, many devices ignore this message. Fortunately, the RawMIDI layer already shuts the device up, so we can ignore this matter here. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
