Takashi Iwai b63f097950 ALSA: seq: oss: Fix racy open/close of MIDI devices ... [ Upstream commit 297224fc09 ] Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be called concurrently from different code paths, we have no proper data protection against races. Introduce open_mutex to each seq_oss_midi object for avoiding the races.
