6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fainelli <florian.fainelli@xxxxxxxxxxxx>
[ Upstream commit 5b76d928f8b779a1b19c5842e7cabee4cbb610c3 ]
Avoid the PHY library call unnecessarily into the suspend/resume
functions by setting phydev->mac_managed_pm to true. The ASP driver
essentially does exactly what mdio_bus_phy_resume() does.
Fixes: 490cb412007d ("net: bcmasp: Add support for ASP2.0 Ethernet controller")
