Subject: [PATCH 2/2] MCI: init device_node for MCI mainarea cdev
Date: Tue,  8 Dec 2015 18:33:29 +0100	[thread overview]
Message-ID: <1449596009-26508-2-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1449596009-26508-1-git-send-email-l.stach@pengutronix.de>

This fixes a regression, where boards specifying the environment
path using the form device-path = &phandle, "partname:part" would
be unable to find their env.

This is due to of_find_path() switching to cdev_by_device_node()
internally, which expects the device_node member of the main
area cdev to be initialized.
