patch "iio: adc: ad7923: Fix undersized rx buffer." added to staging-linus

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

iio: adc: ad7923: Fix undersized rx buffer.

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-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.)
