-ENOTSUPP is not a valid error code, use recommended value instead.
What makes you say this - it's what regmap uses internally for unsupported operations?
This was flagged by scripts/checkpatch.pl (must be a new addition).
# ENOTSUPP is not a standard error code and should be avoided in new patches. # Folks usually mean EOPNOTSUPP (also called ENOTSUP), when they type ENOTSUPP. # Similarly to ENOSYS warning a small number of false positives is expected. if (!$file && $line =~ /\bENOTSUPP\b/) { if (WARN("ENOTSUPP", "ENOTSUPP is not a SUSV4 error code, prefer EOPNOTSUPP\n" . $herecurr) && $fix) { $fixed[$fixlinenr] =~ s/\bENOTSUPP\b/EOPNOTSUPP/; } }
I was just blindly making checkpatch happy and tried to keep regmap-sdw.c and regmap-sdw-mbq aligned.
