2015-01-28ALSA: line6/toneport: Implement LED controls via LED classTakashi Iwai
Instead of non-standard sysfs, reimplement the LED controls on TonePort as LED class devices. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-01-28ALSA: line6: Don't forget to call driver's destructor at error pathTakashi Iwai
Currently disconnect callback is used as a driver's destructor, and this has to be called not only at the disconnection time but also at the error paths during probe. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-28ALSA: line6/toneport: Move setup_timer() at the beginningTakashi Iwai
... so that timer_del_sync() in the destructor can be called safely at any time. Also move the mod_timer() call in toneport_setup(), which is a bit clearer place. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-28ALSA: line6: Remove superfluous NULL checks in each driverTakashi Iwai

2015-01-28ALSA: line6: Abort if inconsistent usbdev is found at disconnectTakashi Iwai
It's utterly unsafe to proceed further the disconnect procedure if the assigned usbdev is inconsistent with the expected object. Better to put a WARN_ON() for more cautions and abort immediately. Tested-by: Chris Rorvick <chris@rorvick.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-01-20ALSA: line6: Sync PCM stop at disconnectTakashi Iwai
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().

2015-01-20ALSA: line6: Reorganize card resource handlingTakashi Iwai
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().

2015-01-20ALSA: line6: Drop invalid SNDRV_PCM_INFO_RESUME flagTakashi Iwai
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>
2015-01-20ALSA: line6: Drop superfluous snd_device for rawmidiTakashi Iwai

2015-01-20ALSA: line6: Handle impulse response via control APITakashi Iwai
