Subject: [PATCH v1 27/28] leds: rt8515: Put fwnode in any case during ->probe()
Date: Mon, 10 May 2021 12:50:44 +0300	[thread overview]
Message-ID: <20210510095045.3299382-28-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20210510095045.3299382-1-andy.shevchenko@gmail.com>

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")
