Driver core: move dev_get/set_drvdata to drivers/base/dd.c
No one should directly access the driver_data field, so remove the field and make it private. We dynamically create the private field now if it is needed, to handle drivers that call get/set before they are registered with the driver core. Also update the copyright notices on these files while we are there. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
