6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Serge Semin <fancer.lancer@xxxxxxxxx>
[ 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.
