I got your point, but checkpatch has no limit for the string literals, see

f4c014c0dede ("checkpatch: allow printk strings to exceed 80 characters to maintain their searchability")
ca56dc098caf ("checkpatch: check for quoted strings broken across lines")

So, what the exact parameters should I supply to it?
