This series is close to be ready for merging.
Two issues: please rebase again to the latest media_stage tree
https://git.linuxtv.org/media_stage.git/
I had a number of conflicts, and I didn't feel comfortable to make the
changes myself, it wasn't trivial.
Secondly, I get a smatch error:
drivers/media/platform/mediatek/mdp3/mdp_cfg_data.c:452 mdp_cfg_get_id_public() error: 'mdp_dev' dereferencing possible ERR_PTR()
In any case, if you can rebase and fix that issue, then I'll make a PR.
Thanks!
