[PATCH 3/3] ACPI / ACPICA: Fail acpi_gpe_wakeup() if ACPI_GPE_CAN_WAKE is unset

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Rafael J. Wysocki <rjw@sisk.pl>

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().
