This is a note to let you know that I've just added the patch titled ASoC: fsl_sai: initialize is_dsp_mode flag to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: asoc-fsl_sai-initialize-is_dsp_mode-flag.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ed6652e28234245edea19b503e953c3313f0db8f Author: Shengjiu Wang <shengjiu.wang@xxxxxxx> Date: Mon Jan 16 15:07:54 2023 +0800 ASoC: fsl_sai: initialize is_dsp_mode flag [ Upstream commit a23924b7dd7b748fff8e305e1daf590fed2af21b ] Initialize is_dsp_mode flag in the beginning of function fsl_sai_set_dai_fmt_tr(). When the DAIFMT is DAIFMT_DSP_B the first time, is_dsp_mode is true, then the second time DAIFMT is DAIFMT_I2S, is_dsp_mode still true, which is a wrong state. So need to initialize is_dsp_mode flag every time. Fixes: a3f7dcc9cc03 ("ASoC: fsl-sai: Add SND_SOC_DAIFMT_DSP_A/B support.")
