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

iio: mma8452: use iio event type IIO_EV_TYPE_MAG

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.

Subject: iio: mma8452: use iio event type IIO_EV_TYPE_MAG

IIO_EV_TYPE_THRESH in rising direction describes an event where the threshold is crossed in rising direction, positive or negative values being possible. This is not the case here.

Since the threshold is no signed value and only the magnitude is compared, IIO_EV_TYPE_MAG is what describes the behaviour of these devices, see the sysfs-bus-iio ABI Documentation.
