 [PATCH v1 1/4] thermal: gov_bang_bang: Call __thermal_cdev_update() directly

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Instead of clearing the "updated" flag for each cooling device
affected by the trip point crossing in bang_bang_control() and
walking all thermal instances to run thermal_cdev_update() for all
of the affected cooling devices, call __thermal_cdev_update()
directly for each of them.

No intentional functional impact.
