Subject: Need to take dev->sem, do it directly or use wrapper?

Greg,

I was looking at restructuring serio a bit and rely more on the
infrastructure in the drivre core now that it is more flexible. It all
looks good except for one detail - serio provides "reconnect" method
which allows user to reinitialize a port whithout tearing down its
children input devices. To properly serialize with probe(), remove() and
other bus operations I'd need to take dev->sem semaphore. I(s bus code
allowed to do this? Can I do it directly or we need to add a wrapper
(like device_serialize_access(dev, bool))?

Thanks.
