* ALSA: line6: fix check on snd_card_registerAditya Pakki2019-01-071-1/+2

| | | | | | | | | In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Declare snd_kcontrol_new strcutures as const as they are only passed as an argument to the function snd_ctl_new1. This argument is of type const, so snd_kcontrol_new structures having this property can be made const too.

* ALSA: line6: Distinguish device init (ctrl EP) and MIDI data transfer (int EP)Andrej Krutak2016-09-191-1/+8
| | | | | | | | POD X3 can initialize similarly to older PODs, but it doesn't have the MIDI interface. Instead, configuration is done via proprietary bulk EP messages. Signed-off-by: Andrej Krutak <dev@andree.sk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | The commit 02fc76f6a changed base of the sysfs attributes from device to card. The "show" callbacks dereferenced wrong objects because of this.

* ALSA: line6: Let snd_card_new() allocate private dataTakashi Iwai2015-01-281-7/+2
| | | | | | | | | 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. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: line6: Drop interface argument from private_init and disconnect callbacksTakashi Iwai2015-01-281-7/+7
| | | | | | | | | | | 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.

* ALSA: line6: Reorganize card resource handlingTakashi Iwai2015-01-201-51/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* ALSA: line6: Drop invalid SNDRV_PCM_INFO_RESUME flagTakashi Iwai2015-01-201-6/+0
| | | | | | | | | | | | 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: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: line6: Split to each driverTakashi Iwai2015-01-201-2/+222
| | | | | | | | | | | 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.
