Hi Julien,

Thank you for the patches.

I'm afraid this doesn't compile based on the latest media tree's master
branch, scheduled for v6.8-rc1. I've pushed the following fixes to [1]:

0d2e75fb8909 media: mediatek: isp_30: Update to new subdev state API
05dc498f151a media: mediatek: isp_30: Update to new subdev state API

You can squash those in v5 when you will rebase on v6.8-rc1.
