From: Arnd Bergmann <arnd@arndb.de>

This is a printf-style function, which gcc -Werror=suggest-attribute=format
correctly points out:

drivers/hwmon/occ/common.c: In function 'occ_init_attribute':
drivers/hwmon/occ/common.c:761:9: error: function 'occ_init_attribute' might be a candidate for 'gnu_printf' format attribute [-Werror=suggest-attribute=format]

Add the attribute to avoid this warning and ensure any incorrect
format strings are detected here.
