ide: kill duplicate code in ide_dump_{ata,atapi}_status()
* Move the common code from ide_dump_{ata,atapi}_status() to ide_dump_status(). * ide_dump_{ata,atapi}_status() -> ide_dump_{ata,atapi}_error(). There should be no functionality changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
