Subject: [PATCH net-next v9 02/15] net: phy: Introduce fwnode_mdio_find_device()
Date: Fri, 11 Jun 2021 13:53:48 +0300 [thread overview]
Message-ID: <20210611105401.270673-3-ciorneiioana@gmail.com> (raw)
In-Reply-To: <20210611105401.270673-1-ciorneiioana@gmail.com>
From: Calvin Johnson <calvin.johnson@oss.nxp.com>
Define fwnode_mdio_find_device() to get a pointer to the
mdio_device from fwnode passed to the function.
Refactor of_mdio_find_device() to use fwnode_mdio_find_device().
