4.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit c894acc7bf400d039bf740420b22f0b71b7fb504 ]
Ensure that when an invalid value in ret or value is found -EINVAL is returned. A previous commit broke the way the return error is being returned and instead caused the return code in ret to be re-assigned rather than be returned.
