However it can also happen that the cleanup path is run > before the transceiver was initialized (or the operating mode isn't set > to TEGRA_USB_OTG) and is therefore NULL. Add a separate label for error > unwinding and initialize the transceiver field to ERR_PTR(-ENODEV) when > the operating mode isn't TEGRA_USB_OTG to allow for consistent checking. This change looks good to me.
