[PATCH 2/5] ACPI: Create symlinks in acpi_bind_one() under physical_node_lock

From: Rafael J. Wysocki
Date: Mon Aug 05 2013 - 20:22:04 EST

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

Put the creation of symlinks in acpi_bind_one() under the
physical_node_lock mutex of the given ACPI device objects, because
that is part of the binding operation logically (those links are
already removed under that mutex too).
