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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafael J. Wysocki <rjw@xxxxxxx>

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().
