Takashi Iwai f24681b816 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.
