proper locking to be checked at runtime. Remove sb_lock() and sb_unlock() calls from sb_reset_dsp() because the latter is called from sb_setup() with the lock already held. Add a call to sb_lockassert(). Surround the call to sb_reset_dsp() in sb16_attach() with sb_lock() and sb_unlock() calls. Tested by: Bartek Marcinkiewicz <junior AT p233.if.pwr.wroc.pl>
