[ Upstream commit445e165889] The function calls of_parse_phandle() which returns a device node with an incremented reference count. When the bonded device is not available, the function returns NULL without releasing the reference, causing a reference leak. Add of_node_put(np) to release the device node reference. The of_node_put function handles NULL pointers. Found through static analysis by reviewing the doc of of_parse_phandle() and cross-checking its usage patterns across the codebase.
