printk(KERN_DEBUG) always produces output, so I used
dev_printk(KERN_DEBUG) to retain that behavior.

dev_dbg() does not always produce output, since it depends on DEBUG or
CONFIG_DYNAMIC_DEBUG and the dynamic debug settings.

If dev_dbg() seems like the right thing, I would probably add a
separate patch on top to convert dev_printk(KERN_DEBUG) to dev_dbg().

Thanks for taking a look!
