From 6658c739431cfa1bdf15737774ed1cac432b5c35 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 27 Oct 2014 13:21:35 +0800 Subject: [PATCH] ACPI: Correct return value of acpi_dev_resource_address_space() Change acpi_dev_resource_address_space() to return failure if the acpi_resource structure can't be converted to an ACPI address64 structure, so caller could correctly detect failure.
