History
Alexander Leidinger 831a62e7e5 - Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page). 
- Remove an assertion in sound.c, it's not needed (and causes a panic now).
  From the conversation via mail between glebius and Ariff:
  ---snip---
  > Well, but which mutex protects now? Do we own anything else
  > in pcm_chnalloc()? I see some queue(4) macros in pcm_chnalloc(),
  > they should be protected, shouldn't they?
  Queue insertion/removal occur during
     1) driver loading (which is pretty much single thread /
        sequential) or unloading (mutex protected, bail out if there is
        any channel with refcount > 0 or busy).
     2) vchan_create()/destroy(), (which is *sigh* quite complicated), but
        somehow protected by 'master'/parent channel mutex. Other
        thread cannot add/remove vchan (or even continue traversing
        that queue) unless it can acquire parent channel mutex.
---snip---

Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).
