Subject: [PATCH v2 0/2] Fix minor issue in SoundWire slave IRQ mapping

Currently there would be problems if multiple devices on the same bus
attempted to use SoundWire IRQ handling rather than the IRQ callback
mechanism. So far only cs42l43 uses this system so this hasn't caused
any problems.

Thanks,
Charles

Changes since v1:
 - Don't reuse the new IDA for the dev_num
 - Expand the number of devices allowed on a bus to 16

Charles Keepax (2):
  soundwire: bus: Simplify sdw_assign_device_num()
  soundwire: bus: Add internal slave ID and use for IRQs
