Takashi Iwai eddfe9672e Revert "ALSA: seq: Protect in-kernel ioctl calls with mutex" 
[ Upstream commit f0654ba94e ]

This reverts commit feb689025f.

The fix attempt was incorrect, leading to the mutex deadlock through
the close of OSS sequencer client.  The proper fix needs more
consideration, so let's revert it now.
