Subject: [PATCH 3/3] of_path: handle no driver for device
Date: Thu, 20 Oct 2016 09:31:22 +0200	[thread overview]
Message-ID: <20161020073122.19295-3-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20161020073122.19295-1-s.hauer@pengutronix.de>

in __of_find_path it can happen that there is a device, but there
is no driver for this device because it hasn't been probed yet.
Return -ENODEV in this case to let the caller know that it has to
try later again.
