    Subject[PATCH 4.19 37/96] iio/gyro/bmg160: Use millidegrees for temperature scale
    Date
    From: Mike Looijmans <mike.looijmans@topic.nl>

    commit 40a7198a4a01037003c7ca714f0d048a61e729ac upstream.

    Standard unit for temperature is millidegrees Celcius, whereas this driver
    was reporting in degrees. Fix the scale factor in the driver.
