securityfs_create_dir strange comment

Hello list,

in security/inode.c, the comment for securityfs_create_dir() reads:

If securityfs is not enabled in the kernel, the value -ENODEV
will be returned. It is not wise to check for this value, but
rather, check for NULL or !NULL instead as to eliminate the need
for #ifdef in the calling code.

What is the actual callee that can return NULL - and what should
module_init() of a module return when securityfs_create_dir() returns
