Subject: [PATCH 08/17] ASoC: SOF: ipc4-pcm: Use the snd_sof_pcm_get_dai_frame_counter() for pcm_delay
Date: Thu, 21 Mar 2024 15:08:05 +0200	[thread overview]
Message-ID: <20240321130814.4412-9-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20240321130814.4412-1-peter.ujfalusi@linux.intel.com>

Switch to the new callback to retrieve the DAI (link) frame counter.
