The dapm_is_shared_control() stuff is about sharing kcontrols between multiple
muxes. This is about sharing the same kcontrol between multiple paths of the
same mixer.
i.e
{ "Mono Mixer", "DAC", "Left DAC" },
{ "Mono Mixer", "DAC", "Right DAC" },
doesn't work without this patch.

The dapm_is_shared_control() stuff is about sharing kcontrols between multiple
muxes. This is about sharing the same kcontrol between multiple paths of the
same mixer.
i.e
{ "Mono Mixer", "DAC", "Left DAC" },
{ "Mono Mixer", "DAC", "Right DAC" },
