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(). Tested-by:

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

Such a debug is needed in the core code, not in each lowlevel driver. Tested-by:

This is rather useless for a driver that has been already merged into the official tree. Tested-by:

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(). Tested-by:

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. Tested-by:

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. Tested-by:

Instead of handling the card-specific resource in snd_device, attach it into pcm->private_data and release it directly in private_free. This simplifies the code and structure. Tested-by:

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. Tested-by:

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. Signed-off-by: -

Which *_disconnect() to call on disconnect is known at initialization. Add a function pointer to the `usb_line6' struct and use to call into the appropriate logic instead of evaluating the conditional logic. Signed-off-by:

Casting the `struct usb_line6' pointer at the call point makes the code difficult to read. This is substantially cleaned up by moving the cast into the callees. Signed-off-by:

The `LINE6_CAP_CTRL_PCM_HW' macro combines three capabilities to save horizontal space when defining the properties entries. Now that these are no longer limited to single lines this is not such a concern. Specify capabilities individually when defining each property for better clarity. Signed-off-by:

Specify the index of the properties entry explicitly to define this structure more robustly. Also, drop the `L6PROP' macro in favor of initializing each member explicitly on its own line since horizontal space is limited and more attributes will be added later. Signed-off-by:

These are now only used to build the device table. Each entry in this table is already clearly documented as to what device it maps to so the macros become unnecessary indirection. Signed-off-by:

The driver currently uses the device's idProduct as input to several switch statements. In some cases this is not sufficiently granular and the interface number must be taken into account. Store the device type in `usb_line6' and key off of it instead. New types can then be added that map to specific interfaces on the device so that this conditional logic can be flattened out.

The current logic uses the index of the matched entry from the device table as an offset to the corresponding properties entry. The values of the new `line6_device_type' enum are ordered such that they can be used as an index into either of these arrays. Drop the device entry lookup logic and use the device type (via the .driver_info member) instead. Signed-off-by:
