Hi Mark, Pierre-Louis Cc each ASoC driver maintainer As we discussed in [1], we don't need to use dpcm_playback/capture flag, so we remove it. But we have been using it for 10 years, some driver might get damage. The most likely case is that the device/driver can use both playback/capture, but have only one flag, and not using xxx_only flag. [1/3] patch indicates warning in such case. And because of its history, DPCM has been checking CPU side only. But it should check Codec side too same as non-DPCM. Some device/driver has been bypassed this check. It should be error. [2/3] patch indicates warning in such case. Because dpcm_xxx flag is no longer used by [1/3] patch, snd_soc_dai_link_set_capabilities() is no longer needed. [3/3] patch remove it. These adds grace time for DPCM cleanup. I'm not sure when dpcm_xxx will be removed, and Codec check bypass will be error, but maybe v6.11 or v6.12 ? Please check each driver by that time.
