Sorry for the delay. Sorry also for the trouble this dummy copy/paste mistake is causing. It's a bit embarrassing even if the intentions are good ;) This second mistake explains why I wasn't getting ill effects from the remove.

The sysfs files were removed backwards as a programmer reflex. In this case it is not really necessary since there are no real dependencies between the function implementations... but there may be in the future. This is why it's a safe habit to do it this way.

I would keep the removal in reverse order,  so I will ack the the v2 patch

Cheers!
