The hd-audio driver gives a few basic tracepoints.
`hda:hda_send_cmd` traces each CORB write while `hda:hda_get_response`
traces the response from RIRB (only when read from the codec driver).
`hda:hda_bus_reset` traces the bus-reset due to fatal error, etc, and
`hda:hda_bus_reset` traces the bus-reset due to fatal error, etc,
`hda:hda_unsol_event` traces the unsolicited events, and
`hda:hda_power_down` and `hda:hda_power_up` trace the power down/up
via power-saving behavior.
