Though regression was not reported, it is actually a regression internally.
It doesn't have a big impact against the hotplug controller that supports 
"command completed interrupt", but it might have a impact against the
controller that doesn't support "command completed interrupt". So I think
it should go into 2.6.27. As you said, the patch looks good and simple.
