Subject: [PATCH v6 09/12] device property: Make dev_fwnode() public
Date: Tue, 28 Mar 2017 10:52:24 +0300 [thread overview]
Message-ID: <1490687547-18311-10-git-send-email-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <1490687547-18311-1-git-send-email-sakari.ailus@linux.intel.com>
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.
