[PATCH 19/38] thermal: Replace deprecated CPU-hotplug functions.

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: 2021-08-03 14:18:03
Also in: lkml
Subsystem: the rest, thermal · Maintainers: Linus Torvalds, Rafael J. Wysocki, Daniel Lezcano

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.
