I've taken a deeper look into the thinkpad acpi module and found a quite
simple solution, which doesnt require deprecated APIs.
The patch is tested against upstream kernel 3.15-rc8 as well as
Ubuntu-3.13.0-29.53.

Hi,
unfortunatly the issue has not been fixed in the latest upstream kernel.
The kernel version I used to test was:
$ uname -r
3.15.0-031500rc8-generic

Out of curiosity I also checked some older kernel images:
3.11.10-031110
12 matches
