This is a generic cleanup series.
Pierre-Louis Bossart (5):
soundwire: stream: uniquify dev_err() logs
soundwire: stream: use consistent pattern for freeing buffers
soundwire: bus: remove sdw_defer argument in sdw_transfer_defer()
soundwire: cadence: use directly bus sdw_defer structure
soundwire: cadence: further simplify low-level xfer_msg_defer()
callback

2.25.1
From: Pierre-Louis Bossart <[email protected]>
The message pointer is already stored in the bus->defer structure, not
need to pass it as an argument.
