Pull ACPI fixes from Rafael Wysocki:
 "These fix a recent regression in the ACPI button driver, add quirks
  related to EC wakeups from suspend-to-idle and fix coding mistakes
  related to the usage of sizeof() in the PPTT parser code:

  Summary:

   - Add suspend-to-idle EC wakeup quirks for Lenovo Go S (Mario
     Limonciello)

   - Prevent ACPI button from sending spurions KEY_POWER events to user
     space in some cases after a recent update (Mario Limonciello)

   - Compute the size of a structure instead of the size of a pointer in
     two places in the PPTT parser code (Jean-Marc Eurin)"
