Doc Text:
The TI AM33xx power management driver in the Linux kernel fails to release reference counts acquired via wkup_m3_ipc_get() when errors occur during probe. Since the corresponding wkup_m3_ipc_put() call is missing from error paths, repeated probe failures gradually exhaust kernel resources.

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

soc: ti: pm33xx: Fix refcount leak in am33xx_pm_probe

wkup_m3_ipc_get() takes refcount, which should be freed by
wkup_m3_ipc_put(). Add missing refcount release in the error paths.
