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.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
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.
