stable inclusion from stable-v6.6.11 commit 3d5a6ed6aa43c4f7220e8ecf06b4fbfcd2c254f3 bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
