Following the discussion from [1], this patchset implements the following: Changelog v2 -> v3: * in patch 'iio: buffer: dmaengine: unwrap the use of iio_buffer_set_attrs()' - minor stylistic change; Changelog v1 -> v2: * rename '{devm_}iio_triggered_buffer_setup()' -> '{devm_}iio_triggered_buffer_setup_ext()' - wrap with macros the new ext functions to preserve backwards compatibility - add a new parameter to the ext functions, which are the buffer->attrs * split into separate patches the removal [from each driver] of iio_buffer_set_attrs() and the switch to a {devm_}iio_triggered_buffer_setup_ext variant * add patch to remove iio_buffer_set_attrs() from DMAEngine IIO buffer * remove the iio_buffer_set_attrs() helper in a final/separate patch * add 'at91-sama5d2_adc: merge buffer & trigger' patch in this series, so that the removal of iio_buffer_set_attrs() is easier to view Alexandru Ardelean (9): iio: buffer: dmaengine: unwrap the use of iio_buffer_set_attrs() iio: adc: at91-sama5d2_adc: merge buffer & trigger init into a function iio: triggered-buffer: add {devm_}iio_triggered_buffer_setup_ext variants iio: accel: adxl372: use devm_iio_triggered_buffer_setup_ext() iio: accel: bmc150: use iio_triggered_buffer_setup_ext() iio: adc: at91-sama5d2_adc: use devm_iio_triggered_buffer_setup_ext() iio: cros_ec: use devm_iio_triggered_buffer_setup_ext() iio: hid-sensors: use iio_triggered_buffer_setup_ext() iio: buffer: remove iio_buffer_set_attrs() helper drivers/iio/accel/adxl372.c | 11 ++- drivers/iio/accel/bmc150-accel-core.c | 25 +++--- drivers/iio/adc/at91-sama5d2_adc.c | 82 +++++++++---------- .../buffer/industrialio-buffer-dmaengine.c | 3 +- .../buffer/industrialio-triggered-buffer.c | 31 ++++--- .../cros_ec_sensors/cros_ec_sensors_core.c | 15 ++-- .../common/hid-sensors/hid-sensor-trigger.c | 22 ++--- drivers/iio/industrialio-buffer.c | 12 --- include/linux/iio/buffer.h | 3 - include/linux/iio/triggered_buffer.h | 23 ++++-- 10 files changed, 113 insertions(+), 114 deletions(-) Reviewed-by: Andy Shevchenko Reviewed-by: Andy Shevchenko
