mm/memory_hotplug.c: drop memory device reference after find_memory_block() [ Upstream commit 89c02e69fc5245f8a2f34b58b42d43a737af1a5e ] Right now we are using find_memory_block() to get the node id for the pfn range to online. We are missing to drop a reference to the memory block device. While the device still gets unregistered via device_unregister(), resulting in no user visible problem, the device is never released via device_release(), resulting in a memory leak. Fix that by properly using a put_device().
