2 things:
- the 2 patches should be squashed together. There is no point having a
single patch for just 2 defines not used anywhere else.
- I believe you don't even need this quirk in the development version of
the hid tree. Would you mind trying a plain v4.12-rcX and report if
you still need the quirk?
Cheers,
Benjamin
