Generally it is recommended to keep strings on a single line for easier
grepping of the code.
"However, never break user-visible strings such as printk messages, because
that breaks the ability to grep for them."

I think in this case it is probably ok because of the %p specifier which can't
really be grepped for...
So I'm ok with this but it might be nice to respin.
Same comment for a couple of places below.
