Just to get the ball rolling, I've made the maintainers entry for you
Huacai :) Perhaps you can pick up the two patches I mentioned earlier in
the thread, as both appear to be fixes?

Thanks,

Subject: [PATCH] MAINTAINERS: add loongson soc driver entry

As a result of there being no entry covering Loongson SoC drivers, some
fixes have fallen through the cracks. Add Huacai Chen as a supporter of
drivers, who will forward patches to the SoC maintainers.
