[PATCH v4 3/3] PM: runtime: Drop DEFINE_FREE() for pm_runtime_put()

From: Rafael J. Wysocki

Date: Fri Sep 26 2025 - 12:27:43 EST


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

The DEFINE_FREE() for pm_runtime_put has been superseded by recently
introduced runtime PM auto-cleanup macros and its only user has been
converted to using one of the new macros, so drop it.
