Hi,
Since in the patch I am not using any pr_* , so I am unable to understand why you are asking for a proper pr_fmt().
I can get rid of the PREFIX . Then should I use pr_* in the patch instead of dev_* ? 
My understanding was dev_* is more preffered than pr_*.
waiting for your suggestion on this.

thanks
