[PATCH net-next v1 1/4] net: mvpp2: Put fwnode in error case during ->probe()

From: Andy Shevchenko
Date: Mon May 10 2021 - 05:58:25 EST

In each iteration fwnode_for_each_available_child_node() bumps a reference
counting of a loop variable followed by dropping in on a next iteration,

Since in error case the loop is broken, we have to drop a reference count
by ourselves. Do it for port_fwnode in error case during ->probe().

Fixes: 248122212f68 ("net: mvpp2: use device_*/fwnode_* APIs instead of of_*")
