From 549e68455c6706796d9d244364dfbf5c575bd1a5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 30 May 2014 04:26:18 +0200 Subject: ACPI / scan: introduce platform_id device PNP type flag 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. Signed-off-by: Rafael J.
