ACPICA: Events: Cleanup of resetting the GPE handler to NULL before removing
ACPICA commit b2b18bb38045404e253f10787b8a4ae6e94cdee6
This patch prevents acpi_remove_gpe_handler() from leaking the stale
gpe_event_info->Dispatch.Handler to the caller to avoid possible NULL pointer
references. Lv Zheng.
