net: phy: at803x: simplify custom phy id matching
The at803x driver contains a function, at803x_match_phy_id(), which tests whether the PHY ID matches the value passed, comparing phy_id with phydev->phy_id and testing all bits that have a "one" in the mask, phydev->drv->phy_id_mask. This is the same test that is used to match the driver, with phy_id replaced with the driver specified ID, phydev->drv->phy_id. Hence, we already know the value of the bits being tested if we look at phydev->drv->phy_id directly, and we do not require a complicated test to check them. Test directly against phydev->drv->phy_id instead. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
