This is a note to let you know that I've just added the patch titled

iio: mma8452: Add missed iio_device_unregister() call in

to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

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.
