The patch still looks broken, and does not belong into the core the
way it is done. We denied hacks like this for good reason. But
out-of-the-blue it was a bluetooth naming regression to fix in the
driver core? Interesting!

If someone is going to add namespaces to 'block' or 'input', the sysfs
layout will break, and userspace will be unable to handle the
resulting changes.
