- Propagate regulator_get_optional() errors so callers can distinguish
    real errors from optional regulators that are absent (Thierry Reding)

  - Propagate devm_of_phy_get() errors so callers can distinguish
    real errors from optional PHYs that are absent (Thierry Reding)

  - Add Andrew Murray as PCI native driver reviewer (Lorenzo Pieralisi)
