From: Bolarinwa Olayemi Saheed <refactormyself@xxxxxxxxx> ioat3_dma_probe() returns PCIBIOS_ error codes from pcie capability accessors. PCIBIOS_ error codes have positive values. Passing on these values is inconsistent with functions which return only a negative value on failure. Before passing on return value of pcie capability accessors, call pcibios_err_to_errno() to convert any positive PCIBIOS_ error codes to negative non-PCI generic error values.
