Subject: [PATCH v2 5/7] ASoC: Intel/SOF: use set_stream() instead of set_tdm_slots() for HDAudio
Date: Fri, 24 Dec 2021 10:10:32 +0800	[thread overview]
Message-ID: <20211224021034.26635-6-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20211224021034.26635-1-yung-chuan.liao@linux.intel.com>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Overloading the tx_mask with a linear value is asking for trouble and
only works because the codec_dai hw_params() is called before the
cpu_dai hw_params().

Move to the more generic set_stream() API to pass the hdac_stream
information.
