Hence this series, after two cleanup patches, introduces a devm_of_phy_optional_get() helper(), and converts existing users of devm_of_phy_get() where appropriate. Changes compared to v1[1]: - Incorporate "[PATCH v2 1/9] phy: Remove unused phy_optional_get()", as it touches the same documentation, - New patch "[PATCH v2 2/9] doc: phy: Document devm_of_phy_get()", - Print an error message in case of failure, as requested by RobH, - Update Documentation, - Clarify removed checks for -ENODEV and -ENOSYS, - Remove error printing in case of real failures from callers, - Rebase am65-cpsw change on top of commit 854617f52ab42418 ("net: ethernet: ti: am65-cpsw: Handle -EPROBE_DEFER for Serdes PHY") in net-next (next-20230123 and later), - Add Reviewed-by, Acked-by. Most of this series been compile-tested only, but the new helper itself has been tested with a new user[2]. Thanks for your comments!
