Hi,
v1 can be found here:
https://lore.kernel.org/all/20211130141815.892354-1-tomi.valkeinen@ideasonboard.com/
Changes in version 2:
- Addressed the review comments
- Fixed two memory leaks
So, no big changes but I wanted to fix the review comments as it's been
over half a year since v1.
And as this depends on the routing and streams kernel support, which is
not merged, this series is not for merging yet.
Tomi

Update the Linux kernel headers for multiplexed streams.
Note: Testing only, and will be regenerated once the API is merged in
the kernel, before merging it in v4l-utils.
