[Mihail Chindris]

Changelog v3 -> v4:
  * https://lore.kernel.org/linux-iio/20210219124012.92897-1-alexandru.ardelean@xxxxxxxxxx
  * Remove DMA related commits
  * Test and add fixies to the previous version
    - Add write function to iio_buffer_fileops in industrialiio-core
    - In iio_kfifo_remove_from change number of samples to 1 instead of
      r->bytes_per_datum otherwise n square samples are removed.
    - In iio_buffer_remove_sample replace move buffer->access->write
      check to first if an replace with remove_from. Checkpatch was
      complaining about returning -ENOSYS
  * Add ad3552r example
