ACPI: autoload modules - Create ACPI alias interface
Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias
like:
grep acpi /lib/modules/2.6.22-rc4-default/modules.alias
alias acpi*:SNY5001:* sony_laptop
alias acpi*:SNY6001:* sony_laptop
for e.g. the sony_laptop module.
This module matches against all ACPI devices with a HID or CID of SNY5001
or SNY6001
Export an uevent and modalias sysfs file containing the string:
[MODALIAS=]acpi:PNP0C0C:
additional CIDs are concatenated at the end.
