Pull ACPI fixes from Rafael Wysocki:
 "These fix a recent ACPICA regression, fix a battery driver regression
  introduced during the 4.17 cycle and fix up the recently added support
  for the PPTT ACPI table.

  Specifics:

   - Revert part of a recent ACPICA regression fix that added leading
     newlines to ACPICA error messages and made the kernel log look
     broken (Rafael Wysocki).

   - Fix an ACPI battery driver regression introduced during the 4.17
     cycle due to incorrect error handling that made Thinkpad 13 laptops
     crash on boot (Jouke Witteveen).

   - Fix up the recently added PPTT ACPI table support by covering the
     case when a PPTT structure represents a processors group correctly
     (Sudeep Holla)"
