Subject: [PATCH AUTOSEL 6.8 06/52] ASoC: SOF: ipc4-pcm: Introduce generic sof_ipc4_pcm_stream_priv
From: Peter Ujfalusi <peter.ujfalusi@...ux.intel.com>
[ Upstream commit 551af3280c16166244425bbb1d73028f3a907e1f ]
Using the sof_ipc4_timestamp_info struct directly as sps->private data
is too restrictive, add a new generic sof_ipc4_pcm_stream_priv struct
containing the time_info to allow new information to be stored in a
generic way.
