'function' is what activity/operation the LED is associated with. It is 
a fixed set of strings which s/w may use. It is a replacement for 
'linux,default-trigger'.

'label' is what is printed next to the LED for a human to read. 'label' 
can be anything and the OS shouldn't care what it is.


They serve 2 different purposes.
