Merge tag 'acpi-5.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull more ACPI updates from Rafael Wysocki:
 "These fix a couple of issues and do some cleanups on top of the
  previous ACPI changes for 5.1-rc1.

  Specifics:

   - Fix a crash caused by unloading an SSDT overlay (Andy Shevchenko)

   - Prevent user space from getting confusing error values on failing
     ACPI sysfs accesses (Rafael Wysocki)

   - Simplify leaf node detection in the PPTT parsing code by using a
     new flag defined in ACPI 6.3 (Jeremy Linton)

   - Add missing "static" in some places in the ACPI configfs code (Andy
     Shevchenko)

   - Fix acpidbg tool path in the ACPI documentation (Flavio Suligoi)"
