One of the issues I have with these quirks is that the burden is on the maintainers to keep them around forever, unless they can prove that it is no longer needed. This is not my call to make, but I would be much less averse to this being merged if we could agree upfront on an expiration time of, say, 2 years (or more?), after which it will be removed (unless anyone makes a very good case for why it needs to be retained). This should be mentioned in the kernel log as well when the quirk is triggered. I still think we should not be using DMI, though. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
