2020-05-18ASoC: codecs: rt1308-sdw: remove duplicate allocationPierre-Louis Bossart
The .read_prop callback is supposed to be called by the SoundWire core only. Calling it again from this driver results in an additional memory allocation for no good reason.

2020-05-18ASoC: codecs: rt*-sdw: fix memory leak in set_sdw_stream()Pierre-Louis Bossart
Now that the sdw_stream is allocated in machine driver, set_sdw_stream() is also called with a NULL argument during the dailink shutdown. In this case, the drivers should not allocate any memory, and just return. Detected with KASAN/kmemleak.

2020-05-18ASoC: codecs: rt*-sdw: don't assign slave_opsPierre-Louis Bossart
The SoundWire bus core already assigns the slave ops, no need to set them a second time manually in each driver.

2020-03-26ASoC: rt1308-sdw: use slot and rx_mask to configure streamPierre-Louis Bossart
If the DAI was configured with a set_tdm_slots() call, use the information. A platform or machine driver may configure each amplifier to extract different bitSlots from the frame, or extract the same data and use processing to generate the relevant output. The latter case is easier to handle in case of orientation changes.
