From 209d3b1743c8187c67cc75dbe9fefbcd3121fba0 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 21 Dec 2012 00:36:48 +0100 Subject: [PATCH] ACPI: Replace ACPI device add_type field with a match_driver flag After the removal of the second argument of acpi_bus_scan() there is no difference between the ACPI_BUS_ADD_MATCH and ACPI_BUS_ADD_START add types, so the add_type field in struct acpi_device may be replaced with a single flag. Do that calling the flag match_driver. Signed-off-by: Rafael J.
