- if (val != EINJ_STATUS_SUCCESS) + if (val == EINJ_STATUS_FAIL) return -EBUSY; + else if (val == EINJ_STATUS_INVAL) + return -EINVAL; The ACPI Specification is really vague here. Documented error codes are 0 = Success (Linux #define EINJ_STATUS_SUCCESS) 1 = Unknown failure (Linux #define EINJ_STATUS_FAIL) 2 = Invalid Access (Linux #define EINJ_STATUS_INVAL) I don't see how reporting -EBUSY for the "Unknown Failure" case is actually better. -Tony
