Subject: [PATCH v2] iio: mma8452: Add missed iio_device_unregister() call in mma8452_probe()
Date: Thu, 28 May 2020 14:41:21 +0800	[thread overview]
Message-ID: <20200528064121.547001-1-hslester96@gmail.com> (raw)

The function iio_device_register() was called in mma8452_probe().
But the function iio_device_unregister() was not called after
a call of the function mma8452_set_freefall_mode() failed.
Thus add the missed function call for one error case.

Fixes: 1a965d405fc6 ("drivers:iio:accel:mma8452: added cleanup provision in case of failure.")
Signed-off-by: Chuhong Yuan <hslester96@gmail.com>

Changes in v2:
  - Add fixes tag.
  - Modify description.
