Hi all,

This is version 17 of the Request API series.

The (minor) changes compared to v16 are:

- Incorporated Tomasz' documentation comments.

- Dropped patch 28/34: "v4l2-mem2mem: Simplify exiting the function in
  v4l2_m2m_try_schedule". This is really independent of the Request API
  and is part of a v4l2-mem2mem patch series from Ezequiel Garcia:

  https://www.mail-archive.com/linux-media@vger.kernel.org/msg133969.html

- Added this patch as it is needed by the cedrus driver:
  https://patchwork.linuxtv.org/patch/50771/

- Rebased to the latest master.

The goal is to get this merged together with a staging cedrus driver for
4.20.

This patch series is also available here:

https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=reqv17

The patched v4l2-compliance (and rebased to the latest v4l-utils
as well) is available here:

https://git.linuxtv.org/hverkuil/v4l-utils.git/log/?h=request

Regards,

	Hans
