Chris Rorvick 12865cac38 ALSA: line6: Pass driver name to line6_probe()
Provide a unique name for each driver instead of using "line6usb" for
all of them.  This will allow for different configurations based on the
driver type.

Takashi Iwai 129b3be689 ALSA: line6: Move the contents of usbdefs.h into driver.h
Most of them are rather relevant with the definitions in driver.h,
and there are only a few lines, so just rip it off.

Takashi Iwai cddbd4f170 ALSA: line6: Tidy up and typo fixes in comments
Just reformatting the comments and typos fixed, no functional
changes.  Particularly,
- avoid the kerneldoc marker "/**",
- reduce multiple comment lines into single lines,
- corrected wrongly referred function names

Takashi Iwai aca514b823 ALSA: line6: Let snd_card_new() allocate private data
Instead of allocating the private data individually in each driver's
probe at first, let snd_card_new() allocate the data that is called in
line6_probe().  This simplifies the primary probe functions.

Takashi Iwai f66fd990c5 ALSA: line6: Drop interface argument from private_init and disconnect callbacks
The interface argument is used just for retrieving the assigned
device, which can be already found in line6->ifcdev.  Drop them from
the callbacks.  Also, pass the usb id to private_init so that the
driver can deal with it there.  This is a preliminary work for the
further cleanup to move the whole allocation into driver.c.

Takashi Iwai 8a3b7c086a ALSA: line6: Remove superfluous NULL checks in each driver
The interface and driver objects are always set when callbacks are
called.  Drop such superfluous NULL checks in init and disconnect
calls of each driver.

Takashi Iwai 85a9339bec ALSA: line6: Reorganize card resource handling
This is a fairly big rewrite regarding the card resource management in
line6 drivers:

- The card creation is moved into line6_probe().  This adds the global
  destructor to private_free, so that each driver doesn't have to call
  it any longer.

- The USB disconnect callback handles the card release, thus each
  driver needs to concentrate on only its own resources.  No need to
  snd_card_*() call in the destructor.

- Fix the potential stall in disconnection by removing
  snd_card_free().   It's replaced with snd_card_free_when_closed()
  for asynchronous release.

- The only remaining operation for the card in each driver is the call
  of snd_card_register().  All the rest are dealt in the common module
  by itself.

- These ended up with removal of audio.[ch] as a result of a reduction
  of one layer.  Each driver just needs to call line6_probe().

Takashi Iwai ccddbe4a99 ALSA: line6: Split to each driver
Split to each individual driver for POD, PODHD, TonePort and Variax
with a core LINE6 helper module.  The new modules follow the standard
ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd,
snd-usb-toneport and snd-usb-variax, together with the corresponding
CONFIG_SND_USB_* Kconfig items.

Promote line6 driver from staging to sound/usb/line6 directory, and
maintain through sound subsystem tree.

This commit just moves the code and adapts Makefile / Kconfig.
The further renames and misc cleanups will follow.
