Thanks for the explanation. Far as I'm concerned patch seems sensible.

Some devices has two sets of accelerometers and the sensor hub exports two hinge angle 'sensors' based on accelerometer values. To allow more than one sensor of the same type, use PLATFORM_DEVID_AUTO instead of PLATFORM_DEVID_NONE when registering platform device for it. Checked on the Lenovo Yoga Book YB1-X91L tablet.
