Subject[RFC PATCH v2 0/5] iio: adc: qcom-spmi-vadc: Propagate fw node label to userspace
Date
Implement read_label in qcom-spmi-vadc to see DT-specified label names
in userspace. At the same time clear up some documentation around
extend_name to promote read_label, and normalize similar code in
qcom-spmi-adc5.

Changes since v1:
- qcom-spmi-vadc: Use read_label instead of extend_name;

New since v1:
- core: Point users of extend_name field to read_label callback
- qcom-spmi-adc5: Use datasheet_name string literal for
iio_chan_spec::datasheet_name;
- qcom-spmi-adc5: Fall back to datasheet_name instead of
fwnode_get_name() for iio_chan_spec::extend_name (gets rid of @xx in
sysfs filenames and labels);
- qcom-spmi-adc5: Remove unnecessary datasheet_name NULL check.

v1: https://lore.kernel.org/linux-arm-msm/20221106193018.270106-1-marijn.suijten@somainline.org/
