| Subject: ALSA: usb-audio: add quirk for Pioneer DDJ-RB |
| |
| From: Hector Martin <marcan@marcan.st> |
| |
| commit 6e8596172ee1cd46ec0bfd5adcf4ff86371478b6 upstream. |
| |
| This is just another Pioneer device with fixed endpoints. Input is dummy |
| but used as feedback (it always returns silence). |
