+Subject: [PATCH 1/2] libinput: evdev.c: use correct fallback value for
+ KEY_LIGHTS_TOGGLE
+
+The kernel defines KEY_LIGHTS_TOGGLE as 0x21e, not 0x160 (which is KEY_OK).

+ KEY_MICMUTE
+
+KEY_MICMUTE was added relatively recently (3.1 with 33009557bd: Add
+KEY_MICMUTE and enable it on Lenovo X220), so provide a fallback definition
+similar to how we do it for KEY_LIGHTS_TOGGLE to fix compilation with older
+toolchains.
