This patch series extends hid-input to support features commonly present in USB HID headsets: 1. Mic mute button and LED. 2. Answer/hangup button and ring/offhook LED(s). These buttons and LEDs are exposed using standard event device interfaces. It allows the VoIP applications in userspace to use the new functionality in a generic device-independent fashion. This series also contains patches for hid-plantronics and hid-jabra to expose the new functionality and work around some hardware quirks, and a fix to hid-input for an issue that prevents the new LED functionality to work with certain headsets. Although checkpatch compains about a few lines, they preserve the same formatting that already exists in hid-input.c.
