This hack is only needed for Huion tablets. It does not seem to have any effect on the other tablets handled by this device right now, but it's better to check for the product id sooner than discovering that we have messed up one tablet later.

Right, I completely forgot about this. That's why it's important to put these things out for testing. However, this should be inverted not just for Huion tablets, but rather for all "enabled" tablets. The UC-Logic TWHA60 v3 inverts that bit as well when enabled, IIRC. We can filter enabled tablets by drvdata->rdesc != NULL, or add an explicit flag.
