LinuxVULNRICHMENT:CVE-2024-36959CVE-2024-36959 pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map()
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.
