3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Laurent Pinchart <laurent.pinch...@ideasonboard.com> commit 31c5f0c5e25ed71eeced170f113bb590f2f1f6f3 upstream. Properly validate the user-supplied index against the number of inputs. The code used the pin local variable instead of the index by mistake.
