From: Serge Semin Date: Thu, 22 Feb 2024 17:58:22 +0000 (+0300) Subject: net: pcs: xpcs: Return EINVAL in the internal methods X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=0f22f30f79a82bfab42680a1bbfc1c90d1f5a6de;p=users%2Fdwmw2%2Flinux.git net: pcs: xpcs: Return EINVAL in the internal methods [ 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. Signed-off-by: Serge Semin Tested-by: Andrew Lunn Signed-off-by: David S.
