ACPI: thinkpad-acpi: add DMI-based modalias
Add DMI-based aliases to allow module autoloading on select thinkpads. The aliases will do nothing unless the dmi-based-module-autoloading.patch patch from Lennart Poettering <mzxreary@0pointer.de> is applied. Lennart's patch has been accepted by greghk and will be merged eventually. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Cc: Lennart Poettering <mzxreary@0pointer.de> Signed-off-by: Len Brown <len.brown@intel.com>
