Hi Sakari,

Thanks for your information.
I'll update the driver later.

Thanks,
Shawn

There's been an API change in how the sub-device try state is stored and accessed. The patch changing the other drivers is:

<URL:https://git.linuxtv.org/sailus/media_tree.git/commit/?id=0d346d2a6f54f06f36b224fd27cd6eafe8c83be9>

Could you make similar changes to the hi847 driver? I'll then squash that patch into the current patch adding the driver.

Kind regards,
