Call line6_pcm_disconnect() at disconnect to make sure that all URBs
are cleared. Also reduce the superfluous snd_pcm_stop() calls from
the function (and remove the unused function) since the streams are
guaranteed to be stopped at this point via snd_card_disconnect().

Calling line6_pcm_disconnect() at suspend callback is superfluous and
rather confusing. Let's get rid of it.

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().

The line6 drivers don't support the full resume although they set
SNDRV_PCM_INFO_RESUME. These flags have to be dropped to inform
properly to the user-space.
Also, drop the CONFIG_PM in trigger callbacks, too, which are rather
superfluous.

Like the previous fix for PCM, attach the card-specific resource into
rawmidi->private_data instead of handling in a snd_device object.
This simplifies the code and structure.

Instead of sysfs and the conditional build with Kconfig, implement the
handling of the impulse response controls via control API, and always
enable the build. Two new controls, "Impulse Response Volume" and
"Impulse Response Period" are added as a replacement for the former
sysfs files.

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.

Do no send MIDI bytes at the full rate at which FireWire packets happen
to be sent, but restrict them to the actual rate of a real MIDI port.
This is required by the specification, and prevents data loss when the
device's buffer overruns.

There are several devices that expect to receive MIDI data only in the
first eight data blocks of a packet. If the driver restricts the data
rate to the allowed rate (as mandated by the specification, but not yet
implemented by this driver), this happens naturally. Therefore, there
is no reason to ever try to use more data packets with any device.

regmap is a library function that gets selected by drivers that need it. No
driver modules should depend on it, since this can create dependency loops.
E.g. if machine driver depends on REGMAP_I2C and selects the CODEC driver
and the CODEC driver selects REGMAP_I2C, then the machine driver selects by
extension one of its dependencies.
The proper way to handle this is for machine drivers to depend on the same
dependencies as the CODEC driver they select. In this case it is I2C.

All DAPM input and output pins of the wm8750 are either used in the card's

Set the fully_routed flag of the card instead of manually marking the unused

cleaner.

In soc_new_compress() when rtd->dai_link->dynamic is set, we create the pcm
substreams with this call:
ret = snd_pcm_new_internal(rtd->card->snd_card, new_name, num,
1, 0, &be_pcm);
which passes 0 as capture_count leading to
be_pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream
being NULL, hence when trying to set rtd a few lines below we get an oops.
Fix by using rtd->dai_link->dpcm_playback and rtd->dai_link->dpcm_capture as
playback_count and capture_count to snd_pcm_new_internal().

There are no more users of this field left so it can finally be removed.
New users should use snd_soc_dapm_to_codec(w->dapm);
The reason why it is removed is because it doesn't fit to well anymore in
the componentized ASoC hierarchy, where DAPM works on the snd_soc_component
level. And the alternative of snd_soc_dapm_to_codec(w->dapm) typically
generates the same amount of code, so there is really no reason to keep it.
For automatic conversion the following coccinelle semantic patch can be used:
// <smpl>

-w->codec
+snd_soc_dapm_to_codec(w->dapm)
