Hi Russell,

While following discussion on your last patchset, it seems you agreed with Hans
to no more rely on the cec-notifier but directly call the dw-hdmi-cec functions.

Anyway, if this patch is merged separately and you still depend on it, you could
still rebase on it when it appears on drm-misc-next...
