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

iio: adc: ad7266: Fix variable checking bug

to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-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 ret variable was not checked after iio_device_release_direct_mode(), which could possibly cause errors
