[ALSA] rawmidi: add get_port_info callback for sequencer information …
Browse files Browse the repository at this point in the history 
…flags

Add a get_port_info callback to the snd_rawmidi_global_ops structure to
allow the USB MIDI driver to supply information flags for the sequencer
ports created by seq_midi.
