Subject: [PATCH 07/17] of: implement of_get_stdoutpath()
Date: Thu,  6 May 2021 11:28:51 +0200	[thread overview]
Message-ID: <20210506092901.25461-8-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>

For deep probe support it will be useful to have a function to
get the node corresponding to the stdoutpath. of_device_is_stdout_path()
already has that functionality in it, so make a separate funcion from
it.
