MT8183's Devicetree describes two eFuse regions: one at 8000000 and another at 11f10000. The efuse at 8000000, unlike the one at 11f10000 and the efuse on all other MediaTek SoCs, does not define any cell, including the socinfo-data ones which the mtk-efuse driver expects to always be present, resulting in the following errors in the log: mtk-socinfo mtk-socinfo.0.auto: error -ENOENT: Failed to get socinfo data mtk-socinfo mtk-socinfo.0.auto: probe with driver mtk-socinfo failed with error -2 The efuse at 8000000 is disabled by default but enabled on mt8183-kukui. Since it is unused, and to prevent the errors from being thrown, disable it on mt8183-kukui. Signed-off-by: Nícolas F. R. A.
