[PATCH] i2c: fsi: Fix a potential leak in fsi_i2c_probe()

[Christophe JAILLET]

In the commit in Fixes:, when the code has been updated to use an explicit
for loop, instead of for_each_available_child_of_node(), the assumption
that a reference to a device_node structure would be released at each
iteration has been broken.

Now, an explicit of_node_put() is needed to release the reference.

Fixes: 095561f476ab ("i2c: fsi: Create busses for all ports")
