Subject[PATCH 10/12] scsi: use device_remove_file_self() instead of device_schedule_callback()
Date
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.
