Friggin magnets, how do those work?  ;-)

I also managed to obtain remote access to a device with an ACPI
i2c-hid device and confirmed that suspend/resume was working and that
I saw no errors, though obviously I couldn't physically interact with
the device remotely.  Hopefully that gives a tiny bit of extra
confidence that the series is OK...

Squashed it into a v9 as well as a local variable rename that I
noticed while looking at the code with fresh eyes.  My v9 also
incorporates the new Goodix timing that I self-commented about on v8.

Crossing fingers that it's all good now.  :-)
