Subject: [PATCH v4 3/5] x86/ioapic: Fix setup_res() failing to get resource
Date: Wed, 17 Aug 2016 16:00:35 +0800	[thread overview]
Message-ID: <1471420837-31003-4-git-send-email-rui.y.wang@intel.com> (raw)
In-Reply-To: <1471420837-31003-1-git-send-email-rui.y.wang@intel.com>

acpi_dev_filter_resource_type() returns 0 on success, and 1 on failure.
A return value of zero means there's a matching resource, so we should
continue within setup_res() to get the resource.
