Possibly this: commit da6752964290567a6b4ea180d1becda75e810e87 Author: David Brownell <[EMAIL PROTECTED]> Date: Tue May 8 00:27:42 2007 -0700 layered parport code uses parport->dev Update some of the layered parport_driver code to use parport->dev: - i2c-parport (parent of i2c_adapter) - spi_butterfly (parent of spi_master, allowing cruft removal) - lp (creating class_device) - ppdev (parent of parportN device) - tipar (creating class_device) There are still drivers that should be updated, like some of the input drivers; but they won't be any worse off than they are today. broke something.
