But what gets displayed here is "Unhandled error code" which is quite misleading as it indicates something that is not addressed by the mid layer. The description string is based on the sense key and sometimes on the additional sense code; since the ACTION_FAIL case always prints the sense key and the additional sense code, this patch removes the description string completely because it does not add useful information.
