This is a note to let you know that I've just added the patch titled
iio: adc: ad7280a: fix ad7280_store_balance_timer()
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.

Use correct argument to iio_str_to_fixpoint() to parse 3 decimal places.
iio_str_to_fixpoint() has a bit of an unintuitive API where the fract_mult parameter is the multiplier of the first decimal place as if it was already an integer. So to get 3 decimal places, fract_mult must be 100 rather than 1000.
