[v4,00/35] media: ti-vpe: cal: improvements towards multistrea

Hi,

This is v4 of the series, previous can be found from:

https://lore.kernel.org/linux-media/20210524110909.672432-1-tomi.valkeinen@ideasonboard.com/

This version is a slightly reduced one, as I've dropped topmost patches
adding multiplexed streams, which need more work and depend on the v4l2
core changes. I have also dropped "media: ti-vpe: cal: use CSI-2 frame
number" as due to racy HW, it very difficult to get right.

Other changes in the version:
- Added missing mutex_destroy()
- Some cosmetic improvements
- Fixed error handling in cal_async_notifier_complete

Everything else but "media: ti-vpe: cal: handle cal_ctx_v4l2_register
error" has a reviewed-by.

I believe this series is ready for merging.

The series is based on Hans' pull request which contains "media:
v4l2-subdev: add subdev-wide state struct".
