   Note that dev_dbg() will only print something if either DEBUG or  
CONFIG_DYNAMIC_DEBUG are defined...

   ... unlike printk(KERN_DEBUG...). You probably want to use pr_debug() instead.

No - this isn't starting a new line.  pr_cont() here.

   Here too... Although wait, it should be KERN_CONT instead! Debug 
levels are only attributed to the whole lines.

And pr_cont() here too.  If you care about using KERN_CONT which is
just a static marker to allow automated printk level checking easier.
