H. Nikolaus Schaller f9f67667e0 power: generic-adc-battery: check for duplicate properties copied from iio channels
commit a427503edaaed9b75ed9746a654cece7e93e60a8 upstream.

If an iio channel defines a basic property, there are duplicate entries
in /sys/class/power/*/uevent.

So add a check to avoid duplicates. Since all channels may be duplicates,
we have to modify the related error check.
