Merge tag 'acpi-6.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull ACPI fixes from Rafael Wysocki:
 "These fix an ACPI APEI error injection driver failure that started to
  occur after switching it over to using a faux device, address an EC
  driver issue related to invalid ECDT tables, clean up the usage of
  mwait_idle_with_hints() in the ACPI PAD driver, add a new IRQ override
  quirk, and fix a NULL pointer dereference related to nosmp:

   - Update the faux device handling code in the driver core and address
     an ACPI APEI error injection driver failure that started to occur
     after switching it over to using a faux device on top of that (Dan
     Williams)

   - Update data types of variables passed as arguments to
     mwait_idle_with_hints() in the ACPI PAD (processor aggregator
     device) driver to match the function definition after recent
     changes (Uros Bizjak)

   - Fix a NULL pointer dereference in the ACPI CPPC library that occurs
     when nosmp is passed to the kernel in the command line (Yunhui Cui)

   - Ignore ECDT tables with an invalid ID string to prevent using an
     incorrect GPE for signaling events on some systems (Armin Wolf)

   - Add a new IRQ override quirk for MACHENIKE 16P (Wentao Guan)"
