Subject: [PATCH v1] PM: runtime: Introduce one more usage counter guard
Date: Wed, 01 Oct 2025 19:34:29 +0200 [thread overview]
Message-ID: <12752072.O9o76ZdvQC@rafael.j.wysocki> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Follow previous commit 9a0abc39450a ("PM: runtime: Add auto-cleanup
macros for "resume and get" operations") and define a runtime PM
usage counter guard in which pm_runtime_get_noresume() and
pm_runtime_put_noidle() will be used for incrementing and
decrementing it, respectively.
