FWIW, I think it's not important to have the message in one line.

I prefer to grep for the message in the object files. This is
especially useful when the same message appears in different places
(e.g., different archs), so I'm sure I only get the ones that are
in my binary

   #!/bin/sh
   find . -name "*.o" -o -name "*.ko" | xargs nm -o | grep $1
