…ents Move the data_ptr and data_size assignments into sof_ipc4_set_get_kcontrol_data() as explicit function parameters instead of having each caller set and clear them on the shared cdata->msg before and after the call.

@bardliao @ujfalusi There's a potential race condition in sof_ipc4_set_get_kcontrol_data(). The shared cdata->msg structure's data_ptr/data_size fields are set by callers before acquiring setup_mutex, and cleared after the IPC call returns. I couldn't reproduce yet, but if @bardliao you can try out? |
