Subject: [PATCH AUTOSEL 4.14 29/67] iio: ad9523: Fix displayed phase

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

[ Upstream commit 5a4e33c1c53ae7d4425f7d94e60e4458a37b349e ]

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.
