Subject: [PATCH] iio: adis16480: fix devices that do not support sleep mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Not all devices supported by this driver support being put to sleep
mode. For those devices, when calling 'adis16480_stop_device()' on the
unbind path, we where actually writing in the SYNC_SCALE register.

Fixes: 80cbc848c4fa0 ("iio: imu: adis16480: Add support for ADIS16490")
Fixes: 82e7a1b250170 ("iio: imu: adis16480: Add support for ADIS1649x family of devices")
