Subject: [PATCH v6 0/6] iio: Add output buffer support

Changelog v5 -> v6:
  * https://lore.kernel.org/all/20210916182914.1810-1-mihail.chindris@analog.com
  * Fix check in  iio_update_buffers adding test on insert_buffer 
  * Return if check in iio_update_buffers fails.
  * Fix length typo
  * Add rb->direction check in both read and write functions.
  * Add fixes tags
  * Add  Reviewed-by: Alexandru Ardelean <ardeleanalex@...il.com> line
  * Remove unnecessary (u8 *) cast
  * Remove unnecessary AD5766_NUM_CH define

Changelog v4 -> v5:
  * https://lore.kernel.org/all/20210820165927.4524-1-mihail.chindris@analog.com
  * Remove ad3552r example from series and replace with the update of an
    existing driver: ad5662. Will add ad3552r in other another series.
  * Make normal comment from kernel-doc comment. (A bot was complaining about that)
  * Add indio_dev->info check 
  * Rename iio_buffer_remove_sample -> iio_pop_from_buffer
  * Fix comment of remove_from: sample -> scan
  * Change iio_pop_from_buffer data type to void * to be consistent with
    iio_push_to_buffers
  * Remove use watermark, in our kernel is not used and I can't think of an
    usecase for it.
  * Reimplement write to increment buffer index and handle blocking and
    noblocking calls
  * Move `if (insert_buffer->direction == IIO_BUFFER_DIRECTION_OUT)` outside lock
  * Remove redundant checks of `if (insert_buffer->direction ==
    IIO_BUFFER_DIRECTION_OUT)`
