We have similar logic in __mdiobus_modify_changed(), but we didn't add its correponding locked variant mdiobus_modify_changed() as we had very few users. Now that we are getting more, let's add the helper. v2: fix build warnings in patch2, add Andrew's RB to patch 1 drivers/net/phy/mdio_bus.c | 22 ++++++++++++++++++++++ drivers/net/phy/phylink.c | 29 ++++------------------------- include/linux/mdio.h | 2 ++ 3 files changed, 28 insertions(+), 25 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
