Subject: [PATCH] ASoC: fsl_sai: initialize is_dsp_mode flag
Date:   Mon, 16 Jan 2023 15:07:54 +0800
Message-Id: <1673852874-32200-1-git-send-email-shengjiu.wang@nxp.com>
Precedence: bulk

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.")
