Subject: [PATCH] net: mdio: fix duplicate registrations for phy with c45 in __of_mdiobus_register()
Date: Sun, 11 Jun 2023 16:58:26 +0800 [thread overview]
Message-ID: <20230611085826.647536-1-zhaojh329@gmail.com> (raw)
In-Reply-To: <20230610161308.3158-1-zhaojh329@gmail.com>
__of_mdiobus_register
__mdiobus_register
mdiobus_scan_bus_c45
of_mdiobus_child_is_phy
of_mdiobus_register_phy
fwnode_mdiobus_register_phy
is_c45 = fwnode_device_is_compatible(child, "ethernet-phy-ieee802.3-c45");
get_phy_device
phy_device_create
This is the function call chain. If a phy is already registered in
mdiobus_scan_bus_c45(), and it's compatible "ethernet-phy-ieee802.3-c45",
thus it will duplicated call get_phy_device later.
