It looks like you're going to have to respin the patchset so I'm adding
my nits even though it's a bit late.

This would look even better as:
switch (mode) {
case AD7091R_MODE_SAMPLE:
conf = 0;
break;
case AD7091R_MODE_COMMAND:
conf = AD7091R_REG_CONF_CMD;
break;
case AD7091R_MODE_AUTOCYCLE:
conf = AD7091R_REG_CONF_AUTO;
break;
default:
return -EINVAL;
}
ret = regmap_update_bits(st->map, AD7091R_REG_CONF,
AD7091R_REG_CONF_MODE_MASK, conf);
if (ret)
return ret;
st->mode = mode;
return 0;

This would be more clear if it were aligned like so:
.mask_separate = BIT(IIO_EV_INFO_VALUE) |
BIT(IIO_EV_INFO_ENABLE),
