Since _SUCCESS (1) and _FAIL (0) are used to indicate the status of the functions. The previous commit 8ae7bf782eacad803f752c83a183393b0a67127b fixed and prevented dereferencing a NULL pointer through checking the return pointer. The NULL pointer check work properly but the return values (-ENOMEM on fail and 0 on success). This work fixed the return values to make sure the caller function will return the correct status.
