ide: add ide_check_atapi_device() helper
* Add ide_check_atapi_device() to ide-atapi.c and convert ide-{floppy,tape}.c to use it instead of ide*_identify_device(). While at it: * Add DRV_NAME defines to ide-{floppy,tape}.c. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
