Neither option is realistic. With endian-checking enabled the qla2xxx
driver triggers so many warnings that it becomes a real challenge to
filter the non-endian warnings out manually:
$ for f in "" CF=-D__CHECK_ENDIAN__; do make M=drivers/scsi/qla2xxx C=2\
$f | &grep -c ': warning:'; done
4
752
If you think it would be easy to fix the endian warnings triggered by
the qla2xxx driver, you are welcome to try to fix these.
