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

iio: adis: set GPIO reset pin direction

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.

Set reset pin direction to output as the reset pin needs to be an active low output pin.
