[PATCH v1 11/17] ALSA: hda: aw88399: Switch to use acpi_bus_get_primary_device()

[Marco Giunta]

> From: "Rafael J. Wysocki" <rafael.j.wysocki at intel.com>
>
> Replace acpi_get_first_physical_node() that is slated for removal
> with acpi_bus_get_primary_device() that takes a reference to the
> device it is about to return.
>
> This addresses a potential use-after-free that may occur if the
> device returned by acpi_get_first_physical_node() is removed right
> after dropping its ACPI companion's physical_node_lock in that
> function.
