Subject: [PATCH] iio: gyro: adis16080: use devm_iio_device_register() in probe
Date:   Mon, 13 Sep 2021 14:53:08 +0300

There is nothing else that needs to be done for this driver. The remove
hook calls only the iio_device_unregister() hook.

So this driver can use devm_iio_device_register() directly.
