 Log Message:
 hdaudio(4): Tighten hdafg_freem.
 
 The fix for PR kern/57890 in hdafg.c 1.29 included more conditionals
 than needed, covering cases that can't happen: if allocm returns
 null, audio(4) does not call freem; and if hdafg_allocm returns
 nonnull, then what audio(4) passes to hdafg_freem had better be
 either the playback or the capture buffer address.
