I'm not looking for the mono/stereo, but looking for the gain value(s) are in
the same register, but in different offset VS gain values are at the same
offset, but in two different registers.
The mono/stereo handling within snd_soc_put_volsw sufficient, and at the
moment the twl6040 has only stereo controls handled this way, but if we have
stereo, it is not a big job to implement.
The macros for SOC_DOUBLE, SOC_DOUBLE_TLV only assignes the .reg, leaving the
.rreg to be zero.
SOC_DOUBLE_R, SOC_DOUBLE_R_TLV on the other hand assigning the .reg, and the
