It did not make it yet downstream in the iio-togreg path. Following [1], where there was a suggestion to name this 'devm_iio_device_attach_new_kfifo_buffer()', I took another look and devm_iio_kfifo_buffer_setup() made more sense, since there is already a '{devm_}iio_triggered_buffer_setup()' helper. This reduces the usage of the iio_device_attach_buffer() helper to a more manage-able state. This is related to comment: https://lore.kernel.org/linux-iio/CA+U=Dsp5hxd9=rNbigUMFALBpPVBqDZDRq_Pe69ggKak7p46=w@mail.gmail.com/T/#u This should have gone before the multibuffer patch-set, but I was still waiting on patch 'iio: adc: ti_am335x_adc: remove omitted iio_kfifo_free()' to make it downstream in iio-togreg. Regarding patch 'iio: kfifo: un-export devm_iio_kfifo_allocate() function' I would have also wanted to un-export iio_kfifo_allocate() & iio_kfifo_free(), but that still needs a bit of work to cleanup the IIO dummy buffer. Related to patchset: https://lore.kernel.org/linux-iio/20201203095005.72252-1-alexandru.ardelean@analog.com/ The IIO dummy driver seems to be one of those blockers in cleaning up some IIO API.
