This is a note to let you know that I've just added the patch titled
iio: frequency: adf4371: Fix output frequency setting
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.)
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.

The fract1 word was not being properly programmed on the device leading to wrong output frequencies.
