This tiny driver does not deserve a different loging scheme from all of
the rest of the kernel.  Just use the dev_* calls directly please, no
need to try to roll your own.  Especially for a 600 line file.

And remove your calls to az_blob_info() that are just debugging stuff,
when the driver is working properly, it is quiet.

thanks,
