When you do, please post this for net, not net-next, since it is a fix. Andrew

A debugfs directory entry is create early during probe(). This entry is not removed on error path leading to some "already present" issues in case of EPROBE_DEFER. Create this entry later in the probe() code to avoid the need to change many 'return' in 'goto' and add the removal in the already present error path.
