From b2972f87508a21db7584d11fdb5c97cb7101a788 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 21 Sep 2009 13:35:24 -0600 Subject: [PATCH] ACPI: remove acpi_device.flags.compatible_ids We now keep a single list of IDs that includes both the _HID and any _CIDs. We no longer need to keep track of whether the device has a _CID.
