If initialization data is available and its fwnode is actually a of_node,
store this information in the led device's structure. This will allow the
device to use or provide OF-based API such (devm_xxx).

It would be step backwards. You can do the conversion in the place of
use i.e. in devm_led_get().
Could be done. But it would break another use case I have. I'm also
working on the regulator support and for this one, of_node needs to be
populated.
Is there a problem populating of_node if the LED is indeed described in
the DT ?
