Hence I made an alternative patch: > https://lore.kernel/org/7b36ac43778b41831debd5c30b5b37d268512195.1686039915.git.geert+renesas@glider.be A better solution would be to re-architect the removal code so that whatever creates the PCS is also responsible for removing it. Also, dwmac_socfpga nees to be reorganised anyway, because it calls stmmac_dvr_probe() which then goes on to call register_netdev(), publishing the network device, and then after stmmac_dvr_probe(), further device setup is done. As the basic driver probe flow should be setup and then publish, the existing code structure violates that. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
