[PATCH v2 0/4] Stylus-on-touchscreen device support

This patchset adds support for stylus-on-touchscreen devices as found on
the OneMix 3 Pro and Dell Inspiron 15 7000 2-in-1 (7591), among others;
with it, they properly behave like a drawing tablet.

Patches 2 and 4 funxionally depend on patch 1.
Patch 4 needs patch 3 to apply.

The output of this patchset and the need for a kernel, rather than
userspace, patch was previously discussed here:
  https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/558#note_792834

Changes in v2:
Patch 4 now ANDs the secondary button with the tip switch,
since it's otherwise borderline useless to the user.

Ahelenia Ziemiańska (4):
  HID: multitouch: require Finger field to mark Win8 reports as MT
  HID: multitouch: set Stylus suffix for Stylus-application devices, too
  HID: input: replace outdated HID numbers+comments with macros
  HID: input: work around Win8 stylus-on-touchscreen reporting
