Subject: device property: Make dev_fwnode() public
From: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>
commit e44bb0cbdc88686c21e2175a990b40bf6db5d005 upstream.
The function to obtain a fwnode related to a struct device is useful for
drivers that use the fwnode property API: it allows not being aware of the
underlying firmware implementation.
