ide: prepare for merging ide-gd-floppy.c with ide-gd.c
- idefloppy_ref_mutex -> ide_disk_ref_mutex - idefloppy_cleanup_obj() -> ide_disk_release() - ide_floppy_get() -> ide_disk_get() - ide_floppy_put() -> ide_disk_put() - ide_floppy_capacity() -> ide_gd_capacity() - ide_floppy_remove() -> ide_gd_remove() - ide_floppy_probe() -> ide_gd_probe() - idefloppy_driver -> ide_gd_driver - idefloppy_open() -> ide_gd_open() - idefloppy_release() -> ide_gd_release() - idefloppy_getgeo() -> ide_gd_getgeo() - idefloppy_media_changed() -> ide_gd_media_changed() - idefloppy_revalidate_disk() -> ide_gd_revalidate_disk() - idefloppy_ops -> ide_gd_ops - idefloppy_init() -> ide_gd_init() - idefloppy_exit() -> ide_gd_exit() - 'floppy' -> 'idkp' in ide_disk_*() and ide_gd_*() - idefloppy_floppy_t -> struct ide_floppy_obj There should be no functional changes caused by this patch.
