Verified that the finger print reader on the Lenovo ThinkPad X13s works
with this series (and not yet merged devicetree changes).

Not sure when or why, but the error message I previously reported seeing
during suspend is now also gone:

dwc3-qcom a4f8800.usb: HS-PHY2 not in L2

Thanks for sticking with it, Krishna.
