Left and Right with a uppercase first letter.

Preferably use a separate variable for each of the enums, keeping track of which array index belongs to which enums is quite cumbersome. E.g.
static SOC_ENUM_SINGLE_DECL(wm8960_adc_left_enum, WM8960_ADDCTL1, ...);

Since this affects the routing these should be DAPM controls. Otherwise you might run into issues with a path being powered down even if it is used.
