Yes, it wasn't hard, at all, just get the id with to_pnp_dev(dev)->id.

However, the chip is buggy, there's no reason to make a compliant
upstream code modify its behavior just due an 'exception' for a not
compliant hardware.
No need to worry about it too though, the workaround is available as I
pointed earlier (Seiji's)...
