Hi Volodymyr

Thanks for your patches.

Please could you include in the subject line which tree it is for. See

Documentation/networking/netdev-FAQ.txt

This seems like the wrong place to do this.

The mapping is created by chip->irq = of_irq_get(np, 0); in
mv88e6xxx_probe(). So the correct place to dispose of this mapping would be in
mv88e6xxx_remove() and the error path of mv88e6xxx_probe().

Thanks
