Project:Branches: Chloe/rtems:fix-dosfs-null-deref to rtems/rtos/rtems:main
Author:   Yang Zhang



## Summary

When creating utf8 or default converters, if memory allocation or 
initialization fails, 'self' becomes NULL. Returning '&self-\>super' results in 
a NULL pointer dereference, which is Undefined Behavior in C. This updates the 
code to explicitly check for NULL before returning.
