Subject: [PATCH 2/2] checkpatch: Fix defect in printk(KERN_<LEVEL> 80 column exceptions

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.
