--------------------------------

commit 4b6d621c upstream.

When calling dev_set_name() memory is allocated for the name for the
struct device.  Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.

Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked.  Fix that leak by manually freeing it right
before the memory for the device is freed.
