DT: leds: Add uniqueness requirement for 'label' property.

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

··· 14 14 - led-sources : List of device current outputs the LED is connected to. The 15 15 outputs are identified by the numbers that must be defined 16 16 in the LED device binding documentation. 17 - - label : The label for this LED. If omitted, the label is 18 - taken from the node name (excluding the unit address). 17 + - label : The label for this LED. If omitted, the label is taken from the node 18 + name (excluding the unit address). It has to uniquely identify 19 + a device, i.e. no other LED class device can be assigned the same 20 + label. 19 21 20 22 - linux,default-trigger : This parameter, if present, is a 21 23 string defining the trigger assigned to the LED. Current triggers are:
