Coincidentally, the checkpatch script does not hit this false positive.
This because a pr_cont actually follows in a #define. It doesn't feel
right but checkpatch does do the correct thing on this one.

This is a valid false positive that I also missed. However, it can
actually be very easily ignored by checking if the format string ends in
%pV. There were about 100 cases in my results that match this.

This isn't an issue for the checkpatch script as it doesn't try to fix
it, it only warns that it is wrong (as it is actually wrong).

This is why I elected to only look at printk, pr_xxx, and dev_xxx in v2
of my patch. So this is another false positive the checkpatch script
would not hit.
