Actually have no idea what does that mean yet. HDA driver itself locked
without using Giant, and I don't know where it comes from. May be from
sound subsystem, maybe from somewhere else. All I have done is created
child device pcm0 from hdac0 and it appeared in a such way. Probably I
had to dig deeper into device creation to understand this.
