Subject: [PATCH] iio: mma8452: add missed iio_device_unregister in probe failure
Date: Wed, 27 May 2020 23:06:06 +0800 [thread overview]
Message-ID: <20200527150606.539130-1-hslester96@gmail.com> (raw)
mma8452_probe() calls iio_device_register() but misses to call
iio_device_unregister() when probe fails.
Add the missed call in error handler to fix it.
