[PATCH 5.14 157/334] leds: rt8515: Put fwnode in any case during ->probe()

[Greg Kroah-Hartman]

From: Andy Shevchenko <andy.shevchenko@xxxxxxxxx>

[ Upstream commit 8aa41952ef245449df79100e1942b5e6288b098a ]

fwnode_get_next_available_child_node() bumps a reference counting of
a returned variable. We have to balance it whenever we return to
the caller.

Fixes: e1c6edcbea13 ("leds: rt8515: Add Richtek RT8515 LED driver")
