The v4l2_device_req_queue() function is a helper that can be used
as the req_queue callback in simple cases: it will walk over all

This patch series is identical to https://patchwork.linuxtv.org/patch/29080/

The only remaining duplicate ops deal with cropping and selection, and I want

Ensure standard format descriptions by filling it in in the v4l2 core.
Currently these descriptions are all over the place and every driver dreams
up its own description. That's not good.
