Split String Checkpatch Warning

[Elizabeth Ferdman <gnudevliz@gmail.com>]

I'm seeing this checkpatch error:

WARNING: quoted string split across lines

example:
MODULE_AUTHOR("Ralph Metzler, Trent Piepho, Ben Pfaff, "
             "Christoph Bartelmus, Andrei Tanas");

Just wondering if this is a good thing to fix, and how do I fix it? I
don't see anything about it in the style guide. If I put the whole
string on one line, it's more than 80 characters. I found one option on
stack overflow that says you can do:

char *my_string = "Line 1 \
                   Line 2";

So I'd be putting a space and a backslash after the line?
I don't know if that conforms with linux kernel coding style though.

I'm also wondering if anyone knows any good resources on common
checkpatch errors and the proper way to fix them. 

Thanks,
Liz
