[ Upstream commit 3c5f655c44bb65cb7e3c219d08c130ce5fa45d7f ]
device_get_next_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.
In the older code the same is implied with device_for_each_child_node().
Fixes: 11e1bbc116a7 ("leds: lm36274: Introduce the TI LM36274 LED driver")
Fixes: a448fcf19c9c ("leds: lm36274: don't iterate through children since there is only one")
