category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e08399e812106c369d9392e7c76a2a66a7b16825



--------------------------------

[ Upstream commit 172c88244b5f2d3375403ebb504d407be0fded59 ]

When a control changes value the return value from _put() should be 1 so
we get events generated to userspace notifying applications of the change.
We are checking if there has been a change and exiting early if not but we
are not providing the correct return value in the latter case, fix this.
