Subject: [PATCH 0/5] iio: kfifo: define a devm_iio_kfifo_buffer_setup helper

This is a re-spin of an older set [1]:
 https://patchwork.kernel.org/project/linux-iio/patch/20200401125936.6398-1-alexandru.ardelean@analog.com/

Patch 'iio: adc: ti_am335x_adc: remove omitted iio_kfifo_free()' is
already be present in a fixes-togreg path. 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 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.

The IIO dummy driver seems to be one of those blockers in cleaning up
some IIO API.
