checkpatch: fix defect in printk(KERN_<LEVEL> 80 column exceptions
Joe Perches [Wed, 25 May 2011 00:13:41 +0000 (17:13 -0700)]
Currently, printk lines with a only KERN_PREFIX and a quoted string
without a comma or close paren that exceed 80 columns are flagged with a
warning.

ie:
printk(KERN_WARNING "some long string that extends beond 80 cols..."
       "and is continued on another line\n");

Allow this form instead of emitting a warning.
