Hi Alex and Cornelia,

We found that the changes are from 2 different patchsets.

[1] 
https://lore.kernel.org/lkml/20230404153452.2405681-1-apatel@ventanamicro.com/
[2] https://www.spinics.net/lists/kernel/msg4791872.html

Patchset 1 is already merged into mainline kernel in v6.4-rc1 and
patchset 2 is not.
Maybe we can split them into two placeholder patches?

Yong-Xuan
