Apparently David now wants me to submit this again --

if (ei_debug)
	pr_debug(...)

David, if that code is acceptable, please let me know.

The only thing I care about is at the moment that you don't do
something that ends up dropping the pr_fmt prefix.

The pr_fmt define at the beginning of the driver is for nothing
if we end up adding exceptions that end up eliding it for no
good reason.  And that's what your patch was doing.
