Subject: [PATCH] leds: aw2013: fix leak of device node iterator
Date: Sat, 26 Sep 2020 01:26:44 +0200	[thread overview]
Message-ID: <20200925232644.GA17005@agrajag.zerfleddert.de> (raw)

In the error path of the for_each_available_child_of_node loop in
aw2013_probe_dt, add missing call to of_node_put to avoid leaking the
iterator.

Fixes: 59ea3c9faf32 ("leds: add aw2013 driver")
Signed-off-by: Tobias Jordan <kernel@cdqe.de>
