At the same time clear up some documentation around extend_name to promote read_label, and normalize similar code in qcom-spmi-adc5. v3 resend: added missing to/cc addresses via b4 prep --auto-to-cc. Changes since v2: - Dropped RFC tag; - Reworded @extend_name deprecation comment. v2: https://lore.kernel.org/r/20230116220909.196926-1-marijn.suijten@somainline.org 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/ --- Marijn Suijten (5): iio: core: Point users of extend_name field to read_label callback iio: adc: qcom-spmi-adc5: Use driver datasheet_name instead of DT label iio: adc: qcom-spmi-adc5: Fall back to datasheet_name instead of fwnode name iio: adc: qcom-spmi-adc5: Remove unnecessary datasheet_name NULL check iio: adc: qcom-spmi-vadc: Propagate fw node label to userspace drivers/iio/adc/qcom-spmi-adc5.c | 15 +++++++-------- drivers/iio/adc/qcom-spmi-vadc.c | 19 ++++++++++++++++++- include/linux/iio/iio.h | 3 +++ 3 files changed, 28 insertions(+), 9 deletions(-) --- base-commit: 92e815cf07ed24ee1c51b122f24ffcf2964b4b13 change-id: 20230502-iio-adc-propagate-fw-node-label-b1fff2e63ae8
