[PATCH 2/2] leds: lp50xx: remove unused regulator

From: Sven Schuchmann
Date: Wed Feb 03 2021 - 03:35:25 EST


The regulator for vled-supply is unused in the driver.
It is just assigned from DT and disabled in lp50xx_remove.
So the code can be removed from the driver.

Part 1 updates the documentation
Part 2 removes the code
