You are developing on some old kernel. You got stale Cc list of at least
three people! How could you for example get "johan+linaro@...nel.org" -
from which maintainer entry - but that at least is not bouncing like two
others.

You must use get_maintainers, not custom templates with fixed outdated
addresses.
