This error handling triggers a Smatch warning:

    drivers/net/ethernet/ti/icssm/icssm_prueth.c:1574 icssm_prueth_probe()
    warn: 'prueth->pru1' is an error pointer or valid

The warning is harmless because the pru_rproc_put() function has an
IS_ERR_OR_NULL() check built in.  However, there is a small bug if
syscon_regmap_lookup_by_phandle() fails.  In that case we should call
of_node_put() on eth0_node and eth1_node.

It's a little bit easier to re-write this code to only free things which
we know have been allocated successfully.
icssm maintainers - please review
Yes you are correct. This got missed somehow sorry about that.

Now the error return is gracefully exiting by freeing the resources.
