This series fixes kcontrol put callback in some of the Tegra drivers which are used on platforms based on Tegra210 and later. The callback is expected to return 1 whenever the HW update is done.

The logic is a little bit another. The 1 means change, so you should compare the register / cached value and return 1 only when a different value is set. Your implementation invokes the change events for duplicate updates.
