[PATCH] leds: netxbig: Fix platform device reference leak on successful probe

[Wentao Liang]

of_find_device_by_node() returns the GPIO extension device with an
elevated reference count.  The error paths release it through the
put_device label, but the success path returns directly, so the
reference is leaked whenever the LED driver probes successfully.

Let the success path fall through to the put_device label.
