Subject: linux/printk.h: use DYNAMIC_DEBUG_BRANCH in pr_debug_ratelimited
pr_debug_ratelimited tests the dynamic debug descriptor the old-fashioned
way, and doesn't utilize the static key/jump label implementation when
CONFIG_JUMP_LABEL is set. Use the DYNAMIC_DEBUG_BRANCH which is defined
appropriately.
