Now let's take the basic tracepoints back to the HD-audio driver. The three bus tracepoints, hda_send_cmd, hda_get_response and hda_unsol_event are revived but in a slightly different form. Since we don't assign the card number there, print the bus device name instead. Signed-off-by: Takashi Iwai <tiwai@suse.de>
