Subject: [PATCH] power: supply: generic-adc-battery: fix unit scaling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ Upstream commit 44263f50065969f2344808388bd589740f026167 ]

power-supply properties are reported in µV, µA and µW.
The IIO API provides mV, mA, mW, so the values need to
be multiplied by 1000.
