Subject: [PATCH] HID: multitouch: add MT_QUIRK_STICKY_FINGERS to MT_CLS_VTL

Hi Benjamin,

Thank you very much for your help on the libinput GitLab issue tracker [1].
Your suggestion to apply MT_QUIRK_STICKY_FINGERS to the VTL class was exactly
what was needed.

This patch fixes the intermittent stuck two-finger scrolling and false
right-clicks that occur on some VTL-class touchpads, specifically my
TOPS0102:00 35CC:0104 device.
The fix has been tested thoroughly on my laptop and works perfectly.

Best regards,
Artem
