The variable gpio_ext_np in the function netxbig_leds_get_of_pdata takes
the value returned by of_parse_phandle; hence, it must be put in order
to prevent a memory leak. Add an of_node_put for gpio_ext_np before a
return statement, and move a pre-existing of_node_put statement to right
after the last usage of this variable.
Issue found with Coccinelle.
