From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
Use scnprintf() to build up a buffer of PNP IDs to print. This
makes the printk atomic and helps get rid of an #ifdef.
Also remove an "#ifdef DEBUG" from some debug functions. The
functions only produce debug output, so it's OK to run the
function and just have the output be dropped at the end.
