Subject: [PATCH] iio: accel: bmc150: Add OF device ID table
Date: Fri,  1 Dec 2017 12:10:58 +0100

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

The I2C device ID table entries have the .driver_data field set, but they
are not used in the driver so weren't set in the OF device table entries.
