[PATCH v3 3/4] chardev: code cleanup for __register_chrdev_region()

It's just code cleanup, not functional change. Signed-off-by: Chengguang Xu --- v1->v2: - Split fix and cleanup patches. - Remove printing minor range in chrdev_show(). v2->v3: - Set variable ret to '-EBUSY' before checking minor range overlap. fs/char_dev.c | 70 +-
