For example, a single register bit that controls separate muxes in both the L and R audio paths. This change updates the code that handles relevant controls to be able to iterate over a list of affected widgets. Note that only the put functions need significant modification to implement the iteration; the get functions do not need to iterate, nor unify the results, since all affected widgets reference the same kcontrol. When creating the list of widgets, always create a 1-sized list, since the control sharing is not implemented in this change.
