[PATCH v6 05/24] iio: kfifo: un-export devm_iio_kfifo_allocate() function

From: Alexandru Ardelean
Date: Mon Feb 15 2021 - 05:41:24 EST


At this point all drivers should use devm_iio_kfifo_buffer_setup() instead
of manually allocating via devm_iio_kfifo_allocate() and assigning ops and
modes.

With this change, the devm_iio_kfifo_allocate() will be made private to the
IIO core, since all drivers should call either
devm_iio_kfifo_buffer_setup() or devm_iio_triggered_buffer_setup() to
create a kfifo buffer.
