What stable tree(s) do you want to see these go into?

Commits were introduced in 5.12, so it should go to all stable trees << 5.12

...

Great, all now queued up.  Sad that qcom didn't want to do this
themselves :(

Thanks for the fixes; I see them in 4.14 and newer stable trees.

But I don't see them in 4.4 and 4.9, nor can I see reason why they
were not applied.

Can someone help?

Thanks,
								Pavel
