Offering: HULK hulk inclusion category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8325 -------------------------------- This patch introduces a new API, `sdei_api_event_status`, to query the status of a specific SDEI event. The function invokes the SDEI firmware call `SDEI_EVENT_STATUS` with the given event number and returns the result.
