From: Julia Lawall julia.lawall@lip6.fr
[ Upstream commit 8c977f5a856a7276450ddf3a7b57b4a8815b63f9 ]
Device node iterators put the previous value of the index variable, so an explicit put causes a double put.
In particular, of_mdiobus_register can fail before doing anything interesting, so one could view it as a no-op from the reference count point of view.
