So the fix is valid. Thanks. Reviewed-by: Claudiu Manoil <claudiu.manoil@nxp.com>

Some resources are allocated using pci_request_region(). It is more straightforward to release them with pci_release_region(). Fixes: 231ece36f50d ("enetc: Add mdio bus driver for the PCIe MDIO endpoint") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- This patch is speculative, mainly based on the inconsistency between some function's names. Using pci_request_mem_regions() would also have things look consistent.
