Subject: checkpatch: fix defect in printk(KERN_<LEVEL> 80 column exceptions
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0fccc6221821e07366aa44bca112c4edb6d04dd7;p=openwrt%2Fstaging%2Fblogic.git

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.
