Following a suggestion by Hans de Goede, I reworked the quirk tables in the i8042 driver. Now all quirks only use a single table. This makes quirks easier to search by device and reduces code line count and memory usage. The 2nd patch adds new debug output to make it easy to see if a specific quirk got applied or not. The third patch adds a list of Clevo devices that need multiple quirks. With the reworked table they don't need to be inserted multiple times now, which was required in v1 and v2 of this patch. I also included the extra quirk for the Clevo NS7xMU, which was a separate patch before.
