Leverage newly introduced 'leds' and 'led-names' properties to pass indicator's phandle and function to v4l2 subnode. The latter supports privacy led since couple of years ago under 'privacy-led' designation. Unlike initially proposed trigger-source based approach, this solution cannot be easily bypassed from userspace, thus reducing privacy concerns.
