> Priit reported that stmmac was crashing with the trace below. This is because > phy_attached_print() is called too early right after the PHY device has been > found, but before it has a driver attached, since that is only done in > phy_probe() which occurs later. > > Fix this by dealing with a possibly NULL phydev->drv point since that can > happen here, but could also happen if we voluntarily did an unbind of the > PHY device with the PHY driver. ... > Tested-By: Priit Laes <pl...@plaes.org> > Fixes: fbca164776e4 ("net: stmmac: Use the right logging function in > stmmac_mdio_register") > Signed-off-by: Florian Fainelli <f.faine...@gmail.com> "net-next"? The commit which introduced this problem is in 'net', don't we want to fix it there?
