Subject: [PATCH v2 11/13] leds: lt3593: Put fwnode in any case during ->probe()
Date: Sat, 29 May 2021 14:19:33 +0300	[thread overview]
Message-ID: <20210529111935.3849707-11-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20210529111935.3849707-1-andy.shevchenko@gmail.com>

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")
