410 * Clear bits in the local doorbell mask register, allowing doorbell interrupts
411 * from being generated for those doorbell bits. If a doorbell bit is already
412 * set at the time the mask is cleared, and the corresponding mask bit is
413 * changed from set to clear, then the ntb driver must ensure that
415 * on clearing the mask bit, then the driver must call ntb_db_event() anyway.
