Subject: [PATCH] leds: lt3593: Put fwnode in any case during ->probe()

[ Upstream commit 7e1baaaa2407a642ea19b58e214fab9a69cda1d7 ]

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

Fixes: 8cd7d6daba93 ("leds: lt3593: Add device tree probing glue")
