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);
