Pull ACPI fixes from Rafael Wysocki:
 "All of these fix recent regressions in ACPICA, in the ACPI PCI IRQ
  management code and in the ACPI AML debugger.

  Specifics:

   - Fix a lock ordering issue in ACPICA introduced by a recent commit
     that attempted to fix a deadlock in the dynamic table loading code
     which in turn appeared after changes related to the handling of
     module-level AML also made in this cycle (Lv Zheng).

   - Fix a recent regression in the ACPI IRQ management code that may
     cause PCI drivers to be unable to register an IRQ if that IRQ
     happens to be shared with a device on the ISA bus, like the
     parallel port, by reverting one commit entirely and restoring the
     previous behavior in two other places (Sinan Kaya).

   - Fix a recent regression in the ACPI AML debugger introduced by the
     commit that removed incorrect usage of IS_ERR_VALUE() from multiple
     places (Lv Zheng)"
