Subject: [PATCH 01/14] net: bcmgenet: Indicate MAC is in charge of PHY PM
Git-commit: bc3410f250219660a7be032c01c954a53b2c26ab
References: git-fixes
Patch-mainline: v6.0-rc1
Avoid the PHY library call unnecessarily into the suspend/resume functions by
setting phydev->mac_managed_pm to true. The GENET driver essentially does
exactly what mdio_bus_phy_resume() does by calling phy_init_hw() plus
phy_resume().
Fixes: fba863b81604 ("net: phy: make PHY PM ops a no-op if MAC driver manages PHY PM")
