Hi,
> This change adds a new hci_uart proto callback entry i.e., power off.

this really has to stop. Read the documentation on how to submit patches and start configuring your .gitconfig correct so that you include you clear text name etc.

I am not extending this. Write a clean serdev only driver for this hardware.
