Yes. What it does is to check that the firmware exposes the service
this driver is using (OPAL_SENSOR_READ). I will fix it.

Here's our solution to this issue.
mcr maintains in its kernel container object an exitcode attribute for
the mcr-restart process. This process is detached from the fork tree
