While the change looks good at first, I am thinking that this might introduce another issue while fixing this one. It looks like the ad7797_attributes[] array may also require the &iio_dev_attr_in_m_in_scale_available.dev_attr.attr attribute as well. It looks like the available scales should be printed for AD7997 as well. That being said, this patch is fine as-is. But it would require a patch [before-this-patch] to fix the ad7797_attributes array. Something like this: static struct attribute *ad7797_attributes[] = { &iio_const_attr_sampling_frequency_available_ad7797.dev_attr.attr, + &iio_dev_attr_in_m_in_scale_available.dev_attr.attr, NULL }; I'm hoping I'm right about this one. I sometimes don't notice things too well. > > Fixes: fd1a8b912841 ("iio:ad7793: Add support for the ad7796 and ad7797") > Signed-off-by: YueHaibing <yuehaibing@xxxxxxxxxx> > --- > drivers/iio/adc/ad7793.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/iio/adc/ad7793.c b/drivers/iio/adc/ad7793.c > index b747db9..e5691e3 100644 > --- a/drivers/iio/adc/ad7793.c > +++ b/drivers/iio/adc/ad7793.c > @@ -542,7 +542,7 @@ static const struct iio_info ad7797_info = { > .read_raw = &ad7793_read_raw, > .write_raw = &ad7793_write_raw, > .write_raw_get_fmt = &ad7793_write_raw_get_fmt, > - .attrs = &ad7793_attribute_group, > + .attrs = &ad7797_attribute_group, > .validate_trigger = ad_sd_validate_trigger, > }; >
