Yeah, was sort of purpose :) (to try to retain the original context of
the question of if the commits should be backported to stable series,
which back then had no need raised)

Right, aplogies. The two commits were
47ea2929d58c35598e681212311d35b240c373ce and
217504a055325fe76ec1142aa15f14d3db77f94f.

47ea2929d58c ("usb: typec: ucsi: acpi: Always decode connector change information")
217504a05532 ("usb: typec: ucsi: Work around PPM losing change information")

and in the followup Benjamin Berg mentioned to pick as well

8c9b3caab3ac26db1da00b8117901640c55a69dd

8c9b3caab3ac ("usb: typec: ucsi: Clear pending after acking connector change"

a related fix later on.

Regards,
Salvatore
