[PATCH] vr41xx: convert to the new platform device interface
The patch does the following for v441xx seris drivers: - stop using platform_device_register_simple() as it is going away - mark ->probe() and ->remove() methods as __devinit and __devexit respectively - initialize "owner" field in driver structure so there is a link from /sys/modules to the driver - mark *_init() and *_exit() functions as __init and __exit Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
