This is my personal opinion, but the code can be simple if all case can be handled in the same way. For example this case, we don't need to care about FE or if (!ch_maps) if all dai_link has ch_maps. Complex case/pattern can be bug entry, IMO. ASoC is already very complex system... And because Codec is dummy, there is no effect for FE if all case handles same way. Thank you for your help !!
