[PATCH 2/3] usb: xhci: tegra: release padctl node reference after probe

[Guangshuo Li]

tegra_xusb_probe() obtains np with of_parse_phandle(), but the successful
path returns without the matching of_node_put(). The probe error path
already releases the reference through the put_padctl label.

Release np before returning from a successful probe so the node reference
is balanced once it is no longer needed.
