Saravana Kannan 47a1161dac net: mdio-mux: Handle -EPROBE_DEFER correctly ... [ Upstream commit 7bd0cef5da ] When registering mdiobus children, if we get an -EPROBE_DEFER, we shouldn't ignore it and continue registering the rest of the mdiobus children. This would permanently prevent the deferring child mdiobus from working instead of reattempting it in the future. So, if a child mdiobus needs to be reattempted in the future, defer the entire mdio-mux initialization. This fixes the issue where PHYs sitting under the mdio-mux aren't initialized correctly if the PHY's interrupt controller is not yet ready when the mdio-mux is being probed. Additional context in the link below. Fixes: 0ca2997d14 ("netdev/of/phy: Add MDIO bus multiplexer support.")
