Original issue is that the id field in the dai is not same as the id in dai_driver when dai driver count == 1. This is due to the legacy dai naming check, which could possibly cause issues if the audio drivers written in assumption that dai->id would be always equal to dai_driver->id. This assumption is true only if the dai driver count is greater than 1, and false if dai driver count is 1. On Qcom Lpass driver we hit such issue while adding support to apq8016.
The code path which falls back to legacy naming for cases where num_dai == 1 does not check if there is any valid information in the dai_driver. This patch fixes that by checking if the dai_driver has valid id and name before falling back to legacy dai naming Although the drivers can work around this issue by only using dai->driver->id, but this patch attempts to fix the actual issue.
