When I tried to merged these patches I got merge conflicts.

Possibly due to other 5.10 changes, but certainly because of conflicts
with patches from Jernej:

https://patchwork.linuxtv.org/project/linux-media/patch/20200825173523.1289379-4-jernej.skrabec@xxxxxxxx/
https://patchwork.linuxtv.org/project/linux-media/patch/20200825173523.1289379-5-jernej.skrabec@xxxxxxxx/

I've merged Jerne's patches and posted a PR for that:
https://patchwork.linuxtv.org/project/linux-media/patch/f3b8e5e2-5f0e-fb6f-e5b2-7f44f7e365e7@xxxxxxxxx/

Can you rebase your patches on top of my branch that contains Jernej's patches?

https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=for-v5.11e

Once my PR is merged into the media_tree master I can take your rebased
patches.

Regards,

	Hans
