It should be /* Codec is dummy */ here. I will post fixup patch, soon. Current simple-card is assuming FE: CPU-dummy BE: dummy-Codec > asoc_simple_canonicalize_platform function where it does say: > = > =BB * DPCM BE can be no platform. > =BB * Alloced memory will be waste, but not leak. > =BB */ > =BB if (!dai_link->platforms->of_node) > =BB =BB dai_link->num_platforms =3D 0; > = > But I do want to create a BE with a platform. So, should I try to > revert the following I see. I'm not using but someone added asoc_simple_parse_platform(). Maybe it can help you (?), but it is not called/used under DPCM case. If you can support it under DPCM, asoc_simple_canonicalize_platform() is no longer your issue ? Thank you for your help !!
