We wrote 1 to the handled interrupts bits along with 0 to all other bits to the SoundWire DPx interrupt register. However, DP0 has reserved fields and the read-only SDCA_CASCADE bit. DPN also has reserved fields. We should not try to write values in these fields. Besides, we deal with pending interrupts in a loop but we didn't reset the slave_notify status.
