Takashi Iwai 288673beae ALSA: usb-audio: Add resume support for MicroII SPDIF ctls
Like the previous fixes, the mixer accessors are converted to use
usb_mixer_elem_list objects.  In addition, the proper shutdown check
are put in get and put callbacks.

Takashi Iwai 0b4e9cfcef ALSA: usb-audio: Add resume support for FTU controls
A few FTU mixer controls have the own value handling, so they have to
be rewritten to follow the support for resume callbacks.  This ended
up in a fair amount of refactoring.  Its own struct is now removed,
instead the values are embedded in kctl private_value totally.

Takashi Iwai da6d276957 ALSA: usb-audio: Add resume support for Native Instruments controls
The changes at this time are a bit more wider than previous ones.
Firstly, the NI controls didn't cache the values, so I had to
implement the caching.  It's stored in bit 24 of private_value.
In addition to that, the initial values have to be read from
registers.

Takashi Iwai 9cf3689bfe ALSA: usb-audio: Add audigy2nx resume support
Rewrite the code to handle LEDs on audigy2nx and co for supporting the
proper resume.  A new internal helper function
add_single_ctl_with_resume() is introduced to manage the
usb_mixer_elem_list more easily.

Also while we're at it, move audigy2nx_leds[] in usb_mixer_interface
struct into the private_value of each kctl, too.

Takashi Iwai 3360b84b8e ALSA: usb-audio: Allow quirks to handle own resume and proc dump
So far, we blindly assumed that the all usb-audio mixer elements
follow the standard and apply the standard resume method for the
registered elements in the id_elems[] list.  However, some quirks
really need the own resume and it's incomplete for now.

This patch enhances the resume handling in two folds:
- split some fields in struct usb_mixer_elem_info into a smaller
  header struct (usb_mixer_elem_list) for keeping the minimal
  information in the linked-list; the usb_mixer_elem_info embeds this
  header struct instead
- add resume and dump callbacks to usb_mixer_elem_list struct to allow
  quirks providing the own methods

For the standard mixer elements, these new callbacks are set to the
standard ones as default, thus there is no functional change by this
patch yet.

The dump and resume callbacks are typedef'ed for ease of later patches
using arrays of such function pointers.

Chris J Arges 76b188c4b3 ALSA: usb-audio: Scarlett mixer interface for 6i6, 18i6, 18i8 and 18i20
This code contains the Scarlett mixer interface code that was originally
written by Tobias Hoffman and Robin Gareus. Because the device doesn't
properly implement UAC2 this code adds a mixer quirk for the device.

Changes from the original code include removing the metering code along with
dead code and comments. Compiler warnings were fixed. The code to initialize
the sampling rate was causing a crash this was fixed as discussed on the
mailing list. Error, and info messages were convered to dev_err and dev_info
interfaces. The custom scarlett_mixer_elem_info struct was replaced with the
more generic usb_mixer_elem_info to be able to recycle more code from mixer.c.

This patch also makes additional modifications based on upstream comments.
Individual control creation functions are removed and a generic
function is no used. Macros for function calls are removed to improve
readability. Hardcoded control initialization is removed. Save to HW
functionality has been removed. Strings for enums are created dynamically for
the mixer. Strings used for controls are now SNDRV_CTL_ELEM_ID_NAME_MAXLEN
length.

Mandar Joshi ca8dc34eaf ALSA: usb-audio - Support for Power/Status LED on Creative USB X-Fi S51
This patch adds support for Power/Status LED on Creative USB X-Fi S51.
There is just one LED on the device. The LED can either be On or it
can be set to Blink. There doesn't seem to be a way to switch it off.
The control message to change LED status is similar to that of
audigy2nx except that the index is to be set to 0 and value is 1 for
Blink and 0 for On.

The 'Power LED' control in alsamixer when muted will cause the LED to
Blink continuously. When unmuted  the LED will stay On. The Creative
driver under Windows sets the LED to blink whenever audio is muted.
This LED can be treated as the CMSS LED but I figured since there is
just one LED, it should be treated as the Power LED. Is that alright?

I've also changed the comment "Usb X-Fi" to "Usb X-Fi S51" as there
are other external X-Fi devices from Creative like Usb X-Fi Go and
Xmod. The volume knob and LED support patch doesn't apply to them.
