A Fixes tag seems necessary according to the commit log, and should
target the net branch using:

[PATCH net] drivers/thunder: improve-warning-message-in-device_for_each_child_node()

Also it seems confusing the 'improve' in the title suggest that it is not
a fix.

Is there any reason you changing the license here?

It seems to be unrelated change here, is the changing related to the
problem you are fixing?

Same here.
