[PATCH v1 16/28] leds: lm36274: Put fwnode in error case during ->probe()

From: Andy Shevchenko
Date: Mon May 10 2021 - 05:52:54 EST


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")
