Expand the device_ids[] array to allow all MMD IDs to be read rather than just the first 8 MMDs, but only read the ID if the MDIO_STAT2 register reports that a device really is present here for these new devices to maintain compatibility with our current behaviour. Note that only a limited number of devices have MDIO_STAT2. 88X3310 PHY vendor MMDs do are marked as present in the devices_in_package, but do not contain IEE 802.3 compatible register sets in their lower space. This avoids reading incorrect values as MMD identifiers. Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.
