Hello Benjamin,
In file 'windfarm_pm121'.c:
If this branch is true:
if (param == NULL) { printk(KERN_WARNING "pm121: %s fan config not found " " for this machine model\n", loop_names[loop_id]); goto fail; }
control that is NULL will suffer a dereference attempt:
fail: /* note that this is not optimal since another loop may still control the same control */ printk(KERN_WARNING "pm121: failed to set up %s loop " "setting \"%s\" to max speed.\n", loop_names[loop_id], control->name);
