[PATCH] ALSA: usb-audio : Add support for the Pioneer DJ DDJ-RR controller.

[Daniel Martin]

Hi Takashi,

It will be a while before I can amend as my Linux PC with the kernel git
gave up the ghost this weekend.
Currently I don't have a PC to access my Arch Linux drive for continuity.

SInce this is just an audio quirk, can you make the necessary
amendments for me in this patch?

Description: Allows the Pioneer DJ DDJ-RR to be seen as a USB audio device
under Linux and therefore usable in such applications as Mixxx.
- Tested Master Audio out, headphones (both output jacks) and microphone
input. All work perfectly.

SIgn-Off-By: Daniel Martin <dmanlfc at gmail.com>

Or alternatively, how can I do this via a web browser in a patch submission
portal?

Thanks in advance,

Dan
