Subject: [PATCH 5/10] ACPI / scan: introduce platform_id device PNP type flag
Date: Fri, 30 May 2014 04:26:18 +0200 [thread overview]
Message-ID: <1831678.FWIeOcOJpB@vostro.rjw.lan> (raw)
In-Reply-To: <35042328.kk6ZUUdfyN@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Only certain types of ACPI device objects can be enumerated as
platform devices, so in order to distinguish them from the others
introduce a new ACPI device PNP type flag, platform_id, and set it
for devices with a valid _HID to start with.
This change is based on a Zhang Rui's prototype.
