[PATCH v2] net: macb: Specify PHY PM management done by MAC

From: Sergiu Moga
Date: Wed Oct 19 2022 - 08:35:03 EST


The `macb_resume`/`macb_suspend` methods already call the
`phylink_start`/`phylink_stop` methods during their execution so
explicitly say that the PM of the PHY is done by MAC by using the
`mac_managed_pm` flag of the `struct phylink_config`.

This also fixes the warning message issued during resume:
WARNING: CPU: 0 PID: 237 at drivers/net/phy/phy_device.c:323 mdio_bus_phy_resume+0x144/0x148

Depends-on: 96de900ae78e ("net: phylink: add mac_managed_pm in phylink_config structure")
Fixes: 744d23c71af3 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state")
