Add HID_USAGE_SENSOR_HUMAN_PRESENCE support for Human Presence sensitivity parsing, in case some implementation uses it as sensitivity modifier. Signed-off-by: Song Hongyan <redacted>
Do we want to perhaps indicate to userspace in some way that this is what is being reported? (not that I have any idea how a proximity sensor could potentially tell a human from a passing cat for example ;) Otherwise, I'm fine with this but would like an Ack from Srinivas.
