The main intent here is to get rid of the iio_buffer_set_attrs() helper, or at least rework it's usage a bit. The problem with that helper is that it needs a pointer to the buffer, which makes supporting multiple buffers per IIO device a bit more cumbersome. The hid_sensor_setup_trigger() is pretty much used in the same way: - iio_triggered_buffer_setup() gets called before - then hid_sensor_setup_trigger() and hid_sensor_setup_batch_mode() gets called which may attach some fifo attributes This change merges the 2 together under the hid_sensor_setup_trigger() function. Only the &iio_pollfunc_store_time is passed to all devices, so it's not even required to pass it explicitly outside of the common hid_sensor_setup_trigger() function. Moving the devm_iio_triggered_buffer_setup/cleanup() calls into the common place code can help the rework of the buffer code, since it is in one place. One detail of the change is that there are 2 drivers that use devm_iio_triggered_buffer_setup(). That function gets implicitly replaced with iio_triggered_buffer_setup()/cleanup(), but since all drivers call both hid_sensor_setup_trigger9) & hid_sensor_remove_trigger() trigger, the iio_triggered_buffer_cleanup() piggy backs on the hid_sensor_remove_trigger() call, which should cover the cleanup.
