Is the clk patch independent from the others? It's not clear to me.

If the clk patch has to go in together with the media patches, then
please let me know and post a v3 where the clk patch is also CC-ed to
the linux-media mailinglist to ensure it ends up in our patchwork system.

And in that case I need a Acked-by from the clk maintainer as well.

If it is independent, then there is no need for a v3 (at least, not
for this).

Regards,
