Subject: [Patch v4 02/16] ACPI: Correct return value of acpi_dev_resource_address_space()
Date: Thu, 28 Aug 2014 10:22:27 +0800 [thread overview]
Message-ID: <1409192561-19744-3-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1409192561-19744-1-git-send-email-jiang.liu@linux.intel.com>
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.
