[alsa-devel] [PATCH 2/3] ASoC: nau8810: add support for nau8812

[Marco Felsch]

The nau8812 device [1] uses exactly the same register layout as the
nau8810 so there is no need to differentiate those. The only difference
is the output power and an additional aux-port input on the nau8812.
The registers related to the aux-port don't affect the nau8810 in a
negative way. They are just ignored (set to '0').
