[PATCH 0/4] reduce Surface Pro 3 multitouch jitter

[Joey Pabalinas]

The Surface Pro 3 firmware doesn't reliably send contact lift off
reports nor handle invalid report values gracefully.

To reduce touchscreen input jitter:
  - add MT_QUIRK_NOT_SEEN_MEANS_UP to the MT_CLS_WIN_8
  - drop invalid report values

Joey Pabalinas (4):
  HID: multitouch: add MT_QUIRK_NOT_SEEN_MEANS_UP to MT_CLS_WIN_8 quirks
  HID: multitouch: don't check HID_GROUP_MULTITOUCH_WIN_8 for serial protocol
  HID: multitouch: drop reports containing invalid values
  HID: multitouch: remove unneeded else conditional cases
