If anyone has any objections, please let me know. ------------------ From: Nikita Shubin commit fdf87a0dc26d0550c60edc911cda42f9afec3557 upstream. Without the terminator, if a con_id is passed to gpio_find() that does not exist in the lookup table the function will not stop looping correctly, and eventually cause an oops.
