In the Linux kernel, the following vulnerability has been resolved:

pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map()

If we fail to allocate propname buffer, we need to drop the reference
count we just took. Because the pinctrl_dt_free_maps() includes the
droping operation, here we call it directly.
