Subject: [PATCH v3 2/2] ARM: OMAP2+: Release device node after it is no longer needed.
Date: Sat,  4 Mar 2017 07:02:11 -0800	[thread overview]
Message-ID: <1488639731-8047-2-git-send-email-linux@roeck-us.net> (raw)
In-Reply-To: <1488639731-8047-1-git-send-email-linux@roeck-us.net>

The device node returned by of_find_node_by_name() needs to be released
after it is no longer needed to avoid a device node leak.
