Sorry did we understand wrong text of Linux coding style? Or do we need
right interpretation of it?

http://www.kernel.org/doc/Documentation/CodingStyle

Statements longer than 80 columns will be broken into sensible chunks.
Descendants are always substantially shorter than the parent and are placed
substantially to the right. The same applies to function headers with a long
argument list. Long strings are as well broken into shorter strings. The
only exception to this is where exceeding 80 columns significantly increases
readability and does not hide information.

void fun(int a, int b, int c)
{
	if (condition)
		printk(KERN_WARNING "Warning this is a long printk with "
						"3 parameters a: %u b: %u "
						"c: %u \n", a, b, c);
	else
		next_statement;
}

Are those lines longer then 80 characters?
Otherwise same applies here.
