ipmi: Don't allow device module unload when in use ...
[ Upstream commit cbb79863fc3175ed5ac506465948b02a893a8235 ]
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.
