Comment 1 for bug 1452473

This also exists upstream.

Looks like the modalias that gets generated is:
$ cat /lib/modules/`uname -r`/modules.alias | grep ibmpowernv
alias platform:opal-sensor ibmpowernv

Where OF creates this for the device:
$ cat /sys/devices/platform/opal-sensor/modalias
of:NsensorsT<NULL>

If I make the module use the OF string it still doesn't seem to work. Patch below:

Any suggestions?
