From: Julien Grall <[email protected]>lu_start() will only set errno when it returns NULL. For all the other cases, the value is unknown. This means that when lu_start() returns an error message, it may not be propagated to the client. The check that errno is a non-zero value is now dropped and instead the value is returned when no error message is provided. This relies on errno to always be set when ret == NULL.
