Subject: printk: add stub for prepend_timestamp()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1fce677971e29ceaa7c569741fa9c685a7b1052a;p=deliverable%2Flinux.git

printk: add stub for prepend_timestamp()

Add a stub for prepend_timestamp() when CONFIG_PRINTK is not
enabled.  Fixes this build error:

kernel/printk.c:1770:3: error: implicit declaration of function 'prepend_timestamp'
