[PATCH] driver core: remove CLASS_ATTR usage

[Greg KH <gregkh@linuxfoundation.org>]

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

There was only 2 remaining users of CLASS_ATTR() so let's finally get
rid of them and force everyone to use the correct RW/RO/WO versions
instead.

PPC maintainers, can I take this in my driver core tree?  I'm doing some
cleanups of device.h and this was one of the simpler ones at the moment.

thanks,
