[PATCH v1 1/1] string: Add missing Return sections

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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")

Cc'ed to the Documentation and kernel-doc people to point out on this
kernel-doc corner cases. It didn't complain on the macros that return
a value. Also it would be nice to have file level consistency on
the naming of the same type of sections, e.g., Returns vs. Return.

Kees, feel free to drop Fixes whilst applying in case you think it not
worth it. The commit message still has a pointer.
