parport: remove driver_data direct access of struct device
Greg Kroah-Hartman [Mon, 4 May 2009 19:40:54 +0000 (12:40 -0700)]
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.
