It doesn't seem to be ack'd by any of the DT maintainers. Retro-actively
changing a DT vendor name would need that, I think.
Thierry and Alex (both Tegra maintainers) appear to have ack'd it, so it
seems they expect it to go through some tree other than Tegra. Weren't
there a bunch of related patches along with this (e.g. updating relevant
drivers to support both prefixes?) so it was expected this patch would
be applied together with them?
