I just tried to apply this patch on v5.15.19 and it applied cleanly for me.

I don't understand. If you know that I'm doing something wrong, can you let me know what it might be?
It fails to build :)
While I have your attention on this, there is another commit that should be back-ported with this. It did not have the "Fixes" tag, unfortunately.
Bjorn has committed it in the "arm64-for-5.18" branch in the Qualcomm repository: git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git 73419e4d2fd1b arm64: dts: qcom: add IPA qcom,qmp property
He says he has no plans to rebase this branch before it gets pulled.
I can send a followup message when that commit lands in v5.18-rc1, but it might be simplest to take care of it now.
According to the stable rules, I have to wait until it hits Linus's tree before I can add it to a stable release.
So if this is a bugfix that everyone needs, it should go to Linus before 5.17-final is out.
thanks,
