Subject: igc: use EOPNOTSUPP instead of ENOTSUPP in igc_ethtool_get_sset_count()
X-Git-Tag: v6.18-rc4~24^2~15^2~1
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=21d08d1c4c29f9795fbc678011c85f72931e22c1;p=thirdparty%2Fkernel%2Fstable.git

igc: use EOPNOTSUPP instead of ENOTSUPP in igc_ethtool_get_sset_count()

igc_ethtool_get_sset_count() returns -ENOTSUPP when a given stringset is
not supported, causing userland programs to get "Unknown error 524".

Since EOPNOTSUPP should be used when error is propagated to userland,
return -EOPNOTSUPP instead of -ENOTSUPP.
