What's the purpose of the "clean up"? Why is it making the code better?

This is a quote from your change:

- PRINTK (KERN_NOTICE, "debug bitmap is %hx", debug &= DBG_MASK);
+ PRINTK (KERN_NOTICE, "debug bitmap is %x", debug &= DBG_MASK);

Are you sure that the use of %hx is the worst part of that line?
