Looks good.  This will happen any time the driver tries to talk to the
card but can't.  So you might want to try looking at whether the card is
already pulled out or its resources have been deallocated before this
code runs.  Obviously we can talk to the card up until it's been pulled
out and the kernel notifies us that the card has been unplugged, but
perhaps there's a codepath that tries to mistakenly handle both
hot-unplug and module removal by writing something to that card (like
reset commands).  I've seen that before in other places.
