Hello Jiaxin Yu,
The patch b65c466220b3: "ASoC: mediatek: mt8186: support adda in platform driver" from May 23, 2022, leads to the following Smatch static checker warning:
sound/soc/mediatek/mt8186/mt8186-dai-adda.c:78 get_adda_priv_by_name() warn: strncmp() with weird length: 17 vs 7
sound/soc/mediatek/mt8186/mt8186-dai-adda.c 72 static struct mtk_afe_adda_priv *get_adda_priv_by_name(struct mtk_base_afe *afe, 73 const char *name) 74 { 75 struct mt8186_afe_private *afe_priv = afe->platform_priv; 76 int dai_id; 77 --> 78 if (strncmp(name, "aud_dac_hires_clk", 7) == 0 || 79 strncmp(name, "aud_adc_hires_clk", 7) == 0)
7 is weird. It would be more readable to say it as:
if (strncmp(name, "aud_dac", 7) == 0 || strncmp(name, "aud_adc", 7) == 0)
80 dai_id = MT8186_DAI_ADDA; 81 else 82 return NULL; 83 84 return afe_priv->dai_priv[dai_id]; 85 }
regards, dan carpenter
