You misunderstood my question. I was asking what specifically, if
anything, was changed in the firmware to allow skipping reset/sleep part
of device initialization on newer parts during resume process. Because
of there were no specific changes I would say let's not do a quirk and
change the driver to skip reset on resume.

Thanks.
