Bug description:
  === SRU Justifications ===

  [Impact]
  Touchpad freezes after a brief usage.

  [Fix]
  Quote from the commit log:
  "The stale cached value written at the final stage undoes the masking.
  Fix this by re-reading the register before clearing the interrupt.

  I also spotted that the interrupt-clearing code can race against
  amd_gpio_irq_mask() / amd_gpio_irq_unmask(), so add locking there.
  Presumably this race was leading to the loss of interrupts."

  [Test Case]
  Touchpad no longer freezes on ideapad 320-15ABR, a new Dell Latitude and
  a new Dell Inspiron.

  [Regression Potential]
  Low. It limits to AMD laptops

  === Original Bug Report ===

  I have installed ubuntu bionic on a Lenovo ideapad 320. The touchpad
  stops working a few seconds after I log in.
