Subject: of: mdio: Add missing inline to of_mdiobus_child_is_phy() dummy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Git-commit: 7df2281a174bd0fdbb2211a26914e5440740fcde
Patch-mainline: v5.5-rc5
References: jsc#SLE-12251

If CONFIG_OF_MDIO=n:

    drivers/net/phy/mdio_bus.c:23:
    include/linux/of_mdio.h:58:13: warning: ‘of_mdiobus_child_is_phy’ defined but not used [-Wunused-function]
     static bool of_mdiobus_child_is_phy(struct device_node *child)
		 ^~~~~~~~~~~~~~~~~~~~~~~

Fix this by adding the missing "inline" keyword.
