Lets get Bob to see if it applies to the latest upstream ACPICA code. Andrew, Do you give Intel permission to accept this patch under both licenses on the top of the file, such that we can re-distribute it in ACPICA to all the OSs that use ACPICA? (hey, and check out the spiffy new acpica home page: http://acpica.org/ ) thanks, -Len On Tuesday 22 January 2008 19:18, Andrew Patterson wrote: > From: Andrew Patterson > > The callback function acpi_ns_get_device_callback called from > acpi_get_devices() will check CID's if the HID does not match.
