Good suggestion, thanks! I'll use dev_err_probe() in the v2, albeit it also calls for turning this into a small patch series that additionally replaces dev_err() with dev_err_probe() in the rockchip_usb2phy_probe() function, for consistency. :) >> ret = devm_extcon_dev_register(rphy->dev, edev); >> if (ret) { >>

Return the actual error code upon failure to allocate extcon device, instead of hardcoding -ENOMEM. While there, produce an appropriate error message.
