Subject: [PATCH v1 5/6] thermal: netlink: Pass thermal zone pointer to notify routines
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
There are several routines in the thermal netlink API that take a
thermal zone ID or a thermal zone type as their arguments, but from
their callers perspective it would be more convenient to pass a thermal
zone pointer to them and let them extract the necessary data from the
given thermal zone object by themselves.
Modify the code accordingly.
No intentional functional impact.
