The problem I have with quirks, and that I explained to Filipe on IRC
is that this is kernel ABI. Even if there is a very low chance we have
someone using this, re-using the same drv_data bit in the future might
break someone's device.

But we can reserve those bits. I don't expect there to be a ton of
devices that need to be quirked, so using the remaining bits should be
perfectly fine. Do you agree?

Nope. If the code is not ready for upstream, it should not be included.

Cheers,
