sfp: fix non-detection of PHY
[ Upstream commit 20b56ed9f8adfb9a7fb1c878878c54aa4ed645c1 ] The detection of a PHY changed in commit e98a3aabf85f ("mdio_bus: don't return NULL from mdiobus_scan()") which now causes sfp to print an error message. Update for this change. Fixes: 73970055450e ("sfp: add SFP module support") Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.
