ide: add ide_retry_pc() helper
* Add ide_create_request_sense_cmd() and ide_retry_pc() helpers and convert ide-{atapi,floppy,tape}.c to use them. * Remove no longer used ide*_create_request_sense_cmd(), ide*_retry_pc() and 'retry_pc' argument from ide_pc_intr(). * Make ide_queue_pc_head() static. There should be no functional changes caused by this patch. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
