ALSA: seq: ump: Notify UMP protocol change to sequencer
UMP v1.1 supports the protocol switch via a UMP Stream message. When it's received, we need to take care of the midi_version field in the corresponding sequencer client, too. This patch introduces a new ops to notify the protocol change to snd_seq_ump_ops for handling it.
