Wysocki Subject: ACPI / PM: Fix build problem when CONFIG_ACPI or CONFIG_PM is not set Commit e5cc8ef (ACPI / PM: Provide ACPI PM callback routines for subsystems) introduced a build problem occuring if CONFIG_ACPI is unset or CONFIG_PM is unset and errno.h is not included before acpi.h, because in that case ENODEV used in acpi.h is undefined. Fix the issue by making acpi.h include errno.h. Signed-off-by: Rafael J.
