This is a note to let you know that I've just added the patch titled
iio:adc:ti-ads124s08: Fix buffer being too long.
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-testing branch.
The patch will show up in the next release of the linux-next tree

Subject: iio:adc:ti-ads124s08: Fix buffer being too long.
The buffer is expressed as a u32 array, yet the extra space for
the s64 timestamp was expressed as sizeof(s64)/sizeof(u16).
This will result in 2 extra u32 elements.
Fix by dividing by sizeof(u32).
