USB Audio Class 1/2 have ability to change device's
volume and mute by USB Host through class-specific control
requests. Device also can notify Host about volume/mute
change on its side through optional interrupt endpoint.
This patch adds Volume and Mute ALSA controls which can be
used by user to send and receive notifications to/from
the USB Host about Volume and Mute change.
These params come from f_uac* so volume and mute controls
will be created only if the function support and enable
each explicitly

Hi Greg,
This change made it to usb-testing and usb-next but there are several
indentation errors in it. By itself, without the rest of the series, it
does not make much sense. It adds a couple of alsa controls but those
actually do nothing without the uac1 and uac2 part of the series.
Maybe it would be better to drop this change until the rest of series is
ready (if this is still possible) ?
The indentation errors were fixed by commit
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/commit/?h=usb-next&id=1bc220835526ae076eecfb7ed513f80f22cf840d
which is in usb-next now too. If possible this commit should be dropped too.
Thanks,
Pavel.
