Subject: [net-next 14/15] net/mlx5: Convert PCI error values to generic errnos

From: Ilpo Järvinen <ilpo.jarvinen@...ux.intel.com>

mlx5_pci_link_toggle() returns mix PCI specific error codes and generic
errnos.

Convert the PCI specific error values to generic errno using
pcibios_err_to_errno() before returning them.
