patch "iio: orientation: hid-sensor-rotation: fix quaternion alignment" added to char-misc-linus

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

iio: orientation: hid-sensor-rotation: fix quaternion alignment

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: orientation: hid-sensor-rotation: fix quaternion alignment

Restore the alignment of sampled_vals to 16 bytes by using IIO_DECLARE_QUATERNION(). This field contains a quaternion value which has scan_type.repeat = 4 and storagebits = 32. So the alignment must be 16 bytes to match the assumptions of iio_storage_bytes_for_si() and also to not break userspace.
