From: Christian Krafft <[email protected]>
When trying to load the ipmi_si module on a powerpc with
no BMC (baseboard management controller) the driver failes to
load correctly, but doesn't unregister itself from of_platform.
So, on a second modprobe the kernel crashes.
This patch adds the missing unregister call.
