A SerDes PHY is optional, so if devm_phy_get() doesn't find one at all, that's fine. But if devm_phy_get() finds a PHY that doesn't have a driver yet, it returns -EPROBE_DEFER. In that case, defer probing the Keystone driver. We may be able to load it later after a PHY driver is loaded. [bhelgaas: changelog, check for -EPROBE_DEFER first] Signed-off-by: NShawn Lin <shawn.lin@rock-chips.com> Signed-off-by: NBjorn Helgaas <bhelgaas@google.com>
