Subject: [PATCH AUTOSEL 5.10 4/7] HID: uclogic: Add HID_QUIRK_HIDINPUT_FORCE quirk

From: José Expósito <jose.exposito89@...il.com>

[ Upstream commit 3405a4beaaa852f3ed2a5eb3b5149932d5c3779b ]

Commit f7d8e387d9ae ("HID: uclogic: Switch to Digitizer usage for
styluses") changed the usage used in UCLogic from "Pen" to "Digitizer".

However, the IS_INPUT_APPLICATION() macro evaluates to false for
HID_DG_DIGITIZER causing issues with the XP-Pen Star G640 tablet.

Add the HID_QUIRK_HIDINPUT_FORCE quirk to bypass the
IS_INPUT_APPLICATION() check.
