I applied both patches to for-5.17 (sorry, I am late, this fell through
the cracks...).

I simplified the commit messages though, especially patch 2, since the
main point of that patch is to introduce support for a new controller
rather than discussing the debounce delay thingy.

If you are OK with it, I will reuse your well written commit message for
a patch removing the debounce delay though :) Working on it now, I will
post something by week end after testing.
