Subject: [PATCH 0/6] Add support for common USB HID headset features

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.

Maxim Mikityanskiy (6):
  HID: hid-input: Add offhook and ring LEDs for headsets
  HID: hid-input: Add phone hook and mic mute buttons for headsets
  HID: plantronics: Expose headset LEDs
  HID: plantronics: Expose headset telephony buttons
  HID: hid-input: Update LEDs in all HID reports
  HID: jabra: Change mute LED state to avoid missing key press events
