Now that flag PHY_HAS_INTERRUPT has been replaced with a check for callbacks config_intr and ack_interrupt, we can remove setting this flag from all driver configs. Last but not least remove flag PHY_HAS_INTERRUPT completely. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
