Hannes Gräuler d2724de187 ALSA: snd-usb-caiaq: LED support for Maschine Controller
This patch adds LED support for the Native Instruments Maschine
Controller. It adds ALSA controls for dimming the LEDs of all
buttons and the backlight of the two displays.

Daniel Mack f1f6b8f65f ALSA: snd-usb-caiaq: switch to dev_*() logging
Get rid of the proprietary functions log() and debug() and use the
generic dev_*() approach. A macro is needed to cast a cdev to a struct
device *.

Daniel Mack 1c8470ce31 ALSA: snd-usb-caiaq: rename 'dev' to 'cdev'
This is needed in order to make the device namespace cleaner, and will
help when moving this driver over to dev_*() logging.

William Light e653510a27 ALSA: snd-usb-caiaq: Add support for Maschine
This adds partial support for the Maschine controller by Native Instruments.
Supported now are the 1x1 MIDI interface and the 41 buttons, 11 endless
rotary encoders, and 16 pressure-sensitive drum pads. Still to work on are the
dimmable LEDs and the two monochrome screens.

Daniel Mack da6094ea7d ALSA: snd_usb_caiaq: track submitted output urbs
The snd_usb_caiaq driver currently assumes that output urbs are serviced
in time and doesn't track when and whether they are given back by the
USB core. That usually works fine, but due to temporary limitations of
the XHCI stack, we faced that urbs were submitted more than once with
this approach.

As it's no good practice to fire and forget urbs anyway, this patch
introduces a proper bit mask to track which requests have been submitted
and given back.

That alone however doesn't make the driver work in case the host
controller is broken and doesn't give back urbs at all, and the output
stream will stop once all pre-allocated output urbs are consumed. But
it does prevent crashes of the controller stack in such cases.

See http://bugzilla.kernel.org/show_bug.cgi?id=40702 for more details.

Daniel Mack 15c5ab6070 ALSA: snd-usb-caiaq: Add support for Traktor Kontrol S4
This patch adds support for the new Traktor Kontrol S4 by Native
Instruments. It features a new audio data streaming model, MIDI
in and out ports, a huge number of 174 dimmable LEDs, 96 buttons
and 46 absolute encoder axis, including some rotary encoders.

All features are supported by the driver now.

Did some code refactoring along the way.

This device does not have audio controllers and backlit buttons only.
Input data is handled over a dedicated USB endpoint.

All functions are supported by the driver now.
