We're in the v6.12 merge window right now, so please post this again after v6.12-rc1 (probably Sep 29). In subject and commit log, s/Added/Add/.

While creation of device link, if devm_phy_get() function fails then it directly returns PTR_ERR without any cleanup of previous added device links. Added goto statement when devm_phy_get() fails, to handle the cleanup of already added device links.
