Looks Good.

The one thing that is bothering me though, is that for
__dynamic_dev_dbg(), __dynamic_netdev_dbg(), we are copying much of the core
logic of __dev_printk(), __netdev_printk(), respectively. I would prefer
have this in one place. Can we add a 'prefix' argument to __dev_printk(),
and __netdev_printk() that dynamic debug can use, but is simply empty
for dev_printk() and netdev_printk().

Thanks,
