[PATCH v3 2/3] phy: phy-rockchip-inno-usb2: Handle failed extcon allocation better

[Dragan Simic]

Return the actual error code upon failure to allocate extcon device, instead
of hardcoding -ENOMEM.  Use dev_err_probe() to also log appropriate messages,
which is fine because the containing function is used in the probe path.
