Entry for JMTek LLC., SSS USB Headphone Set in the quirk table.

Please add an explaination why this entry is needed. At first glance, this entry seems to describe a class-compliant device that should not need a quirk.

+/* JMTek, LLC. SSS USB Headphone Set */ +{

• .match_flags = USB_DEVICE_ID_MATCH_DEVICE |

•        USB_DEVICE_ID_MATCH_DEV_CLASS |
  

•        USB_DEVICE_ID_MATCH_INT_CLASS |
  

•        USB_DEVICE_ID_MATCH_INT_SUBCLASS,
  

• .idVendor = 0x0c76,
• .idProduct = 0x1605,
• .bDeviceClass = USB_CLASS_PER_INTERFACE,
• .bInterfaceClass = USB_CLASS_AUDIO,
• .bInterfaceSubClass = USB_SUBCLASS_AUDIO_CONTROL
