There were a few places that pr_debug() had to be used (or it can be changed back to dprintk()) because they are cleanup functions and do not have any devices available at the cleanup. If there is a better way to handle that, I will go back and make a modification to that. Other than those 3 spots, dev_dbg() is being used. --- Ian Cowan
