Where can I find the netlist firmware packages that go with the android driver?

I have it in my queue to fix that too, the register doesn't exist on a couple of the other chips we support too. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
