The cause of this is that who_am_i for the motion sensors read back as
0xff on that phone. It means a physical issue with one of the SPI
signals or maybe the GSENSOR_3V3... we can explain it that this means
that "the test works" and that particular phone is busted for motion
sensors :-)

We use a canned /dev and no udev in this filesystem, so the files always
exist alright.
