Revert "ppdev: use new parport device model"
This reverts commit e7223f18. It causes problems when a ppdev tries to register before the parport driver has been registered with the device model. That will trigger the BUG_ON(!drv->bus->p); at drivers/base/driver.c:153. The call chain is kernel_init -> kernel_init_freeable -> do_one_initcall -> ppdev_init -> __parport_register_driver -> driver_register *BOOM* Reported-by: Nkernel test robot <fengguang.wu@intel.com> Reported-by: NRoss Zwisler <zwisler@gmail.com> Reported-by: NPetr Mladek <pmladek@suse.com> Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
