Subject: [PATCH 4.9 22/63] iio: ad9523: Fix displayed phase

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@...afoo.de>

commit 5a4e33c1c53ae7d4425f7d94e60e4458a37b349e upstream.

Fix the displayed phase for the ad9523 driver. Currently the most
significant decimal place is dropped and all other digits are shifted one
to the left. This is due to a multiplication by 10, which is not necessary,
so remove it.
