Subject: [PATCH] perf: Replace acpi_bus_get_device()
Date: Tue, 01 Feb 2022 20:10:01 +0100	[thread overview]
Message-ID: <10025610.nUPlyArG6x@kreacher> (raw)

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

Replace acpi_bus_get_device() that is going to be dropped with
acpi_fetch_acpi_dev().

No intentional functional impact.
