ide-floppy: ->{srfp,wp} -> IDE_AFLAG_{SRFP,WP}
Add IDE_AFLAG_{SRFP,WP} drive->atapi_flags and use them instead of ->{srfp,wp} struct ide_floppy_obj fields. There should be no functional changes caused by this patch. Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
