Apologies for leaving the first three of those off. James and Martin are
already seeing the submission to linux-scsi and linux-kernel.

My changes was purposely meant to be minimal. I though about adding a
macro for debug printing with ratelimit, but since there were only two
cases where that would be used, and I was trying for minimal change, I
didn't redesign the debugging statements.

But I'm happy to withdraw my submission and support yours, since it also
fixes the problem.

In this case, if this was my driver, I'd be tempted to optimize this
even further and ifdef out that debug code, since it's so ridiculously
verbose when used.

If you submit this, please cc me so I can withdraw my submission.
