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.
