Greg Kroah-Hartman c619140d48 debugfs: fix debugfs_rename parameter checking ... commit d88c93f090 upstream. debugfs_rename() needs to check that the dentries passed into it really are valid, as sometimes they are not (i.e. if the return value of another debugfs call is passed into this one.) So fix this up by properly checking if the two parent directories are errors (they are allowed to be NULL), and if the dentry to rename is not NULL or an error.
