A coccicheck run provided information like the following: drivers/pinctrl/sirf/pinctrl-sirf.c:798:2-8: ERROR: missing put_device; call of_find_device_by_node on line 792, but without a corresponding object release within this function. Generated by: scripts/coccinelle/free/put_device.cocci Thus add a jump target to fix the exception handling for this function implementation.
