Char: rocket, fix dynamic_dev tty
- register_device unconditionally (non-pci dependent) to have also isa devices in /dev - unregister devices on module removal - don't set TTY_DRIVER_DYNAMIC_DEV twice (removed the one dependent on some macro) Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: Ferenc Wagner <wferi@niif.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
