[PATCH 10/12] scsi: use device_remove_file_self() instead of device_schedule_callback()
driver-core now supports synchrnous self-deletion of attributes and the asynchrnous removal mechanism is scheduled for removal. Use it instead of device_schedule_callback(). This makes "delete" behave synchronously. Signed-off-by: Tejun Heo Cc: "James E.J.
