Subject: [PATCH 0/3] power: supply: ab8500: Improve code related to iio_read_channel_processed() and fix a bug

This series is inspired by a patch submitted at [1].

While looking if the same pattern was relevant elsewhere, I ended in
ab8500_charger.c.

Patch 1 fixes what looks to me as a regression introduced by
97ab78bac5d0.

Patch 2 is the initial goal of this series. That is to change some
iio_read_channel_processed() + multiplication by a single, cleaner,
iio_read_channel_processed_scale().

Patch 3 is a cosmetic change spotted while at it.

Honestly, I don't have a strong opinion if patch 2 helps in any way
(explanation or confirmation would be appreciated for my own
knowledge), but at least patch 1 deserves a look and seems value to me.
