Subject: [PATCH v2 13/13] leds: sgm3140: Put fwnode in any case during ->probe()
Date: Sat, 29 May 2021 14:19:35 +0300	[thread overview]
Message-ID: <20210529111935.3849707-13-andy.shevchenko@gmail.com> (raw)
In-Reply-To: <20210529111935.3849707-1-andy.shevchenko@gmail.com>

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

Fixes: cef8ec8cbd21 ("leds: add sgm3140 driver")
