Subject: printk: add KERN_CONT annotation
X-Git-Tag: v2.6.24-rc1~583
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4749252776712e587c7c7619cbf0342b080c7f44;p=karo-tx-linux.git

printk: add KERN_CONT annotation

printk: add the KERN_CONT annotation (which is empty string but via
which checkpatch.pl can notice that the lacking KERN_ level is fine).
This useful for multiple calls of hand-crafted printk output done by
early debug code or similar.
