The kernel-doc unfortunately can't catch some corner cases. Hence
the commit 645b9ad2dc6b ("string: Add missing kernel-doc return descriptions")
missed that. On top there is no consistency in use of Return/Returns.
Address both problems here. Choose Returns over Return as it will be
less invasive change.

Fixes: 645b9ad2dc6b ("string: Add missing kernel-doc return descriptions")
