device create: ieee1394: convert device_create to device_create_drvdata
device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Cc: Ben Collins <ben.collins@ubuntu.com> Acked-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
