[PATCH 13/14] ide-cd: use whole request_sense buffer in EH

Borislav Petkov
2009-05-09T07:49:51Z

Now that we use a static request_sense buffer, use it instead of the
first 18 bytes only. Also, remove sense-arg to cdrom_analyze_sense_data
and cdrom_log_sense since we can access it through drive->sense_data
now.
