I do not like to argue with you, but I do not think what you said is
right, there are double standards here.

The code are rebased frequently by you in linux-loongson.git, the latest
is after 6.18-rc5 that is in this week, my patch is also rebased.

You accepted the suggestion of your patch v1 title [1] and send v2 [2]
although v1 has been applied by Andrew, because you think it is a good
suggestion.

I just do the similar and right thing,  but your reply is not polite
and friendly, and also do not do the thing what you should to do as a
maintainer.
