Takashi Iwai e311782acd ALSA: hda - Re-add tracepoints to HD-audio core driver 
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.

Takashi Iwai d068ebc25e ALSA: hda - Move some codes up to hdac_bus struct 
A few basic codes for communicating over HD-audio bus are moved to
struct hdac_bus now.  It has only command and get_response ops in
addition to the unsolicited event handling.

Note that the codec-side tracing support is disabled temporarily
during this transition due to the code shuffling.  It will be
re-enabled later once when all pieces are settled down.
