ASoC: SOF: Intel: hda-ipc: read all IPC registers first Align with hardware recommended sequences, and read all IPC registers before doing any other actions. Playing with BUSY and DONE bits may invalidate values. The values read may not actually be necessary but at least this provides a snapshot of the IPC registers with no consistency issues.
