Before we take the hammer, could you share the report descriptors (or
I'll request those in the kernel BZ)?
In the kernel BZ, it's clear that the report descriptor is wrong at
assigning axes, but I'd like to double check if applying the quirk
will be OK and will not pollute other axes.

Cheers,
Benjamin
