From bfa54812f0bc802819051b4084cd07a3d467ce79 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Mon, 6 Jun 2022 22:02:08 +0200 Subject: net: phy: fixed_phy: set phy_mask before calling mdiobus_register() There's no point probing for phys on this artificial bus, so we can save a little bit of boot time by telling mdiobus_register() not to do that. This doesn't have any functional change, since, at this point, fixed_mdio_read() returns 0xffff for all addresses/registers, so mdiobus_scan() -> get_phy_device() -> get_phy_c22_id() will return -ENODEV, which is just ignored.
