I guess so because you are using strange settings... What do you want to do ?
this is just an example setting to reproduce the issue with current mainline kernel,
We have enabled TDM Split and Ex-Split mode in our kernel, and SSI(U)'s dma address diffs based on the BUSIF it is using, so have a single dma data struct per rsnd_ssi will cause issue when SSI isn't working with BUSIF0.
Do you have any suggestion to address this issue?
Thanks, Jiada
