OSPM executes an EXECUTE_OPERATION action to instruct the platform to begin the injection operation, then executes a GET_COMMAND_STATUS action to determine the status of the completed operation. The ACPI Specification documented error codes[1] are: 0 = Success (Linux #define EINJ_STATUS_SUCCESS) 1 = Unknown failure (Linux #define EINJ_STATUS_FAIL) 2 = Invalid Access (Linux #define EINJ_STATUS_INVAL) The original code report -EBUSY for both "Unknown Failure" and "Invalid Access" cases. Actually, firmware could do some platform dependent sanity checks and returns different error codes, e.g. "Invalid Access" to indicate to the user that the parameters they supplied cannot be used for injection. To this end, fix to return -EINVAL in the __einj_error_inject() error handling case instead of always -EBUSY, when explicitly indicated by the platform in the status of the completed operation.
