Subject: printk: declare printk_ratelimit_state in ratelimit.h
From: Namhyung Kim <namhyung@xxxxxxxxx>
Adding declaration of printk_ratelimit_state in ratelimit.h removes
potential build breakage and following sparse warning:
kernel/printk.c:1426:1: warning: symbol 'printk_ratelimit_state' was not declared. Should it be static?
