Title:
  Goodix touchpad may drop first input event

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Committed
Status in linux source package in Disco:
  Fix Committed
Status in linux source package in Eoan:
  Fix Released

Bug description:
  [Impact]
  If a touchpad is connected to Intel LPSS PCI device, sometimes the first tap 
event can be dropped. Goodix touchpad has a rather small buffer so the time its 
parent devices spend in resuming need to be small.

  [Fix]
  Remove Intel LPSS D3cold delay, which is the bottleneck of the situation.

  [Test]
  Intel had tested the patch and the result is positive.

  [Regression Potential]
  Low. Intel internally tested this so it should be rather safe.
