<linux/i2c.h> already provides structs i2c_device_id and of_device_id.
So please drop the explicit include for <linux/mod_devicetable.h>, as
this will go away soon.

Please use named initializers and saner code style. I suggest:

	static const struct i2c_device_id inv_icm42370_id[] = {
		{ .name = "icm42370", .driver_data = INV_CHIP_ICM42370 },
		{ }
	};

	.id_table = inv_icm42370_id,
