If something has the IPMI driver open, don't allow the device module to be unloaded. Before it would unload and the user would get errors on use.
This change is made on user request, and it makes it consistent with the I2C driver, which has the same behavior.
It does change things a little bit with respect to kernel users. If the ACPI or IPMI watchdog (or any other kernel user) has created a user, then the device module cannot be unloaded. Before it could be unloaded,
This does not affect hot-plug. If the device goes away (it's on something removable that is removed or is hot-removed via sysfs) then it still behaves as it did before.
I don't think this is good idea for stable. First, it includes unrelated function rename, and second, it does not really fix any bug; it just changes behaviour.
