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

iio: adc: ad7768-1: Fix insufficient alignment of timestamp.

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.

On architectures where an s64 is not 64-bit aligned, this may result insufficient alignment of the timestamp and the structure being too small. Use aligned_s64 to force the alignment.

Fixes a1caeebab07e ("iio: adc: ad7768-1: Fix too small buffer passed to iio_push_to_buffers_with_timestamp()") # aligned_s64 newer
