ACPI fixes for 5.11-rc3

Browse Source 
- Drop two local variables that are never read and the code updating
    their values from the x86 suspend-to-idle code (Rafael Wysocki).
 
  - Add empty stub of an ACPI helper function to avoid build issues
    when CONFIG_ACPI is not set (Shawn Guo).
 
  - Remove confusing text regarding modules from Kconfig entries that
    correspond to non-modular code (Peter Robinson).

Merge tag 'acpi-5.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
 "These address two build issues and drop confusing text from a couple
  of Kconfig entries.

  Specifics:

   - Drop two local variables that are never read and the code updating
     their values from the x86 suspend-to-idle code (Rafael Wysocki)

   - Add empty stub of an ACPI helper function to avoid build issues
     when CONFIG_ACPI is not set (Shawn Guo)

   - Remove confusing text regarding modules from Kconfig entries that
     correspond to non-modular code (Peter Robinson)"
