[PATCH 13/38] hwmon: Replace deprecated CPU-hotplug functions.

From: Sebastian Andrzej Siewior
Date: Tue Aug 03 2021 - 10:17:50 EST


The functions get_online_cpus() and put_online_cpus() have been
deprecated during the CPU hotplug rework. They map directly to
cpus_read_lock() and cpus_read_unlock().

Replace deprecated CPU-hotplug functions with the official version.
The behavior remains unchanged.
