patch "iio: imu: st_lsm6dsx: wait for settling time in" added to char-misc-linus

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

iio: imu: st_lsm6dsx: wait for settling time in

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: st_lsm6dsx: wait for settling time in
st_lsm6dsx_read_oneshot

We need to wait for sensor settling time (~ 3/ODR) before reading data in st_lsm6dsx_read_oneshot routine in order to avoid corrupted samples.
