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. Reviewed-by: Parvathi Pudi <parvathi@couthit.com> Thanks and Regards, Parvathi.
