  Hi,

These are the first 6 patches from the "[PATCH v10 00/38] v4l: subdev
internal routing and streams" series. I'm posting these as a separate
series, as the active state patches are a separate topic from the
multiplexed streams.

There are changes in these patches compared to the v10 series in the
docs and comments. The only functional change is in the
v4l2_subdev_lock_and_return_state() function, where we now:

	if (!state)
		dev_notice_once(sd->dev, "source subdev should be ported to new state management\n");

I don't particularly like the text there, so if anyone has better
suggestions...

 Tomi
