ACPI / ACPICA: Fail acpi_gpe_wakeup() if ACPI_GPE_CAN_WAKE is unset
Make acpi_gpe_wakeup() return error code for GPEs whose ACPI_GPE_CAN_WAKE flag is not set. This way acpi_gpe_wakeup() will only wake for the GPEs reported by the host OS as "wakeup" ones with the help of acpi_gpe_can_wake(). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
