[systemd-devel] [PATCH] keymap: Add microphone mute keymap for Dell Latitude

[Hui Wang]

On the Dell Latitude, the mic mute key event is generated by wmi
driver, the keycode assigned to this hotkey from kernel is
KEY_MICMUTE (248), this keycode is too big for xorg to handle,
in the xorg, the XF86AudioMicMute is assigned to F20.

Please refer to 4e648ea0 of xkeyboard-config.
