How do you think about another wording variant?

   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.

Would you like to add the tag “Fixes” to the commit message?

Regards,
Markus
