It's a bit unrelated comment to this change, but it may be worth to verify all
kcontrol put callbacks in the tegra code. Ensure that value 1 is returned only
when something was really changed in hardware.
The tegra210_i2s_put_control() has opposite problem for example - returns
always 0 which means that the change notifications are not send to subscribed
applications.
