This is a note to let you know that I've just added the patch titled
iio: imu: fxos8700: fix failed initialization ODR mode assignment
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.

Subject: iio: imu: fxos8700: fix failed initialization ODR mode assignment
The absence of correct offset leads a failed initialization ODR mode
assignment.
Select MAX ODR mode as the initialization ODR mode by field mask and
FIELD_PREP.
