From e44bb0cbdc88686c21e2175a990b40bf6db5d005 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Tue, 28 Mar 2017 10:52:24 +0300 Subject: [PATCH] device property: Make dev_fwnode() public 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.
