Subject[PATCH 5.0 048/117] hwmon: (occ) Fix power sensor indexing
Date
From: Eddie James <eajames@linux.ibm.com>

commit 8e6af454117a51dbf6c8a47c00180a0c235052fe upstream.

In the case of power sensor version 0xA0, the sensor indexing overlapped
with the "caps" power sensors, resulting in probe failure and kernel
warnings. Fix this by specifying the next index for each power sensor
version.

Fixes: 54076cb3b5ff ("hwmon (occ): Add sensor attributes and register ...")
