The .min_sel and .max_sel fields remained uninitialized in the new
linear_range, causing an error further down the line. Copy the old
values of these fields to the new one as they represent the range of
register values, which does not change.

Titas reports that the accelerometer sensor on their laptop only
works after a warm boot or unloading/reloading the amd-sfh kernel
module.
Presumably the sensor is in a bad state on cold boot and failing to
start, so explicitly stop it before starting.
