If anyone has any objections, please let me know. ------------------ From: Felix Gu [ Upstream commit c0b4a4feeb43305a754893d8d9c6b2b5a52d45ac ] When calling of_parse_phandle_with_fixed_args(), the caller is responsible to call of_node_put() to release the reference of device node. In pinbank_init(), the reference of the node obtained from the "gpio-ranges" property is never released, resulting in a reference count leak. Add the missing of_node_put() call to fix the leak.
