If we reuse the struct snd_soc_card, the card .name will be same. Should I change the card .name through of_device_is_compatible()? Maybe like below: Remove rt5682x related words for snd_soc_card. static struct snd_soc_card mt8192_mt6359_rt1015p_card = { .owner = THIS_MODULE, .dai_link = mt8192_mt6359_dai_links, .num_links = ARRAY_SIZE(mt8192_mt6359_dai_links), .controls = mt8192_mt6359_rt1015p_controls, .num_controls = ARRAY_SIZE(mt8192_mt6359_rt1015p_controls), .dapm_widgets = mt8192_mt6359_rt1015p_widgets, .num_dapm_widgets = ARRAY_SIZE(mt8192_mt6359_rt1015p_widgets), .dapm_routes = mt8192_mt6359_rt1015p_routes, .num_dapm_routes = ARRAY_SIZE(mt8192_mt6359_rt1015p_routes), }; static const struct of_device_id mt8192_mt6359_dt_match[] = { { .compatible = "mediatek,mt8192_mt6359_rt1015_rt5682", .data = &mt8192_mt6359_rt1015_rt5682_card, }, { .compatible = "mediatek,mt8192_mt6359_rt1015p_rt5682", .data = &mt8192_mt6359_rt1015p_card, }, { .compatible = "mediatek,mt8192_mt6359_rt1015p_rt5682s", .data = &mt8192_mt6359_rt1015p_card, }, {} }; if (of_device_is_compatible(np, "mediatek, mt8192_mt6359_rt1015p_rt5682")) { card.name = "mt8192_mt6359_rt1015p_rt5682"; ... } else if (of_device_is_compatible(np, "mediatek, mt8192_mt6359_rt1015p_rt5682s")) { card.name = "mt8192_mt6359_rt1015p_rt5682s"; ... }
