The error handling isn't correct because checking "&hs->hs_group"
for NULL doesn't work.  "hs" and "&hs->hs_group" are the same
address and we checked "hs" already.  If we wanted to check for
allocation errors, then we would need to change the check to:

        if (!hs->hs_group.cg_item.ci_name)
		kfree(hs);

But that's not how the function is supposed to be used.  The example
code in Documentation/filesystems/configfs/configfs_example_explicit.c
doesn't have error handling.
