Would be nice if you picked one place and kept it there. (I believe this is partly because of how the previous revision had some more complicated functions added nearby that were related. But you've killed that now.) > > /** > * rockchip_pcie_parse_dt - Parse Device Tree > @@ -883,12 +896,8 @@ static int rockchip_pcie_parse_dt(struct rockchip_pcie *rockchip) > if (IS_ERR(rockchip->apb_base)) > return PTR_ERR(rockchip->apb_base); > > - rockchip->phy = devm_phy_get(dev, "pcie-phy"); > - if (IS_ERR(rockchip->phy)) { > - if (PTR_ERR(rockchip->phy) != -EPROBE_DEFER) > - dev_err(dev, "missing phy\n"); > + if (rockchip_pcie_get_phys(rockchip)) > return PTR_ERR(rockchip->phy); In the next patch you (correctly) change this to actually capture the return code from rockchip_pcie_get_phys(). Seems like you should just do that in this patch.
