The implementations for enum and value enum controls are almost identical. The only difference is that the value enum uses an additional look-up table to map the control value to the register value, while the enum control uses a direct mapping. Enums and value enums can easily be distinguished at runtime, for value enums the values field of the snd_soc_enum struct contains the look-up table, while for enums it is NULL. This patch adds two new small helper functions called snd_soc_enum_item_to_val() and snd_soc_enum_val_to_item() which map between register value and control item. If the items field of the snd_soc_enum struct is NULL the function will do a direct mapping otherwise they'll use the look-up table to do the mapping. Using these small helper functions it is possible to use the same kcontrol handlers for both enums and value enums. The functions are added a inline functions in soc.h so they can also be used by the DAPM code to accomplish similar consolidation.
