From 78b8e141f8458ba0b8ac53c45bc327112c53887e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 21 Sep 2009 13:35:04 -0600 Subject: ACPI: fix synthetic HID for \_SB_ This makes \_SB_ show up as /sys/devices/LNXSYSTM:00/LNXSYBUS:00 rather than "device:00". This has been broken for a loooong time (at least since 2.6.13) because device->parent is an acpi_device pointer, not a handle.
