[v2,01/18] xattr: Remove unnecessary NULL attribute name check

Commit Message

Andreas Gruenbacher May 20, 2016, 11:14 a.m. UTC

When NULL is passed to one of the xattr system calls as the attribute
name, copying that name from user space already fails with -EFAULT;
xattr_resolve_name is never called with a NULL attribute name.
