Marc Kleine-Budde d005a09edf phylib: phy_attach_direct: phy_init_hw can fail, add cleanup ... The function phy_attach_direct attaches the phy and calls phy_init_hw. phy_init_hw can fail, but the phy is still marked as attached. Successive calls to phy_attach_direct will fail because the phy is busy.
