Pull up following revision(s) (requested by riastradh in ticket #898):
        sys/dev/pci/hdaudio/hdaudio.c: revision 1.2
Initialize dma.dma_sizereg to avoid copying uninitialized data later.
This field is not actually used here -- not clear it should be in
the hdaudio_dma structure at all.
Noted by Coverity, CID 979553.
