[ Upstream commit f5151005d379d9ce42e327fd3b2d2aaef61cda81 ]
In particular the xpcs_soft_reset() and xpcs_do_config() functions currently return -1 if invalid auto-negotiation mode is specified. That value might be then passed to the generic kernel subsystems which require a standard kernel errno value. Even though the erroneous conditions are very specific (memory corruption or buggy driver implementation) using a hard-coded -1 literal doesn't seem correct anyway especially when it comes to passing it higher to the network subsystem or printing to the system log. Convert the hard-coded error values to -EINVAL then.
