Subject: [PATCH 2/8] ACPI: PM: Use the new device_to_pm() helper to access struct dev_pm_ops
Date: Mon, 25 May 2020 18:26:02 +0000 [thread overview]
Message-ID: <20200525182608.1823735-3-kw@linux.com> (raw)
In-Reply-To: <20200525182608.1823735-1-kw@linux.com>
Use the new device_to_pm() helper to access Power Management callbacs
(struct dev_pm_ops) for a particular device (struct device_driver).
No functional change intended.
