Driver core: move the static kobject out of struct driver
This patch removes the kobject, and a few other driver-core-only fields out of struct driver and into the driver core only. Now drivers can be safely create on the stack or statically (like they currently are.) Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
