Like this?

static void exynos4210_sanitize_temp_error(struct exynos_tmu_data *data,
					   u32 trim_info)
{
	data->temp_error1 = trim_info & EXYNOS_TMU_TEMP_MASK;
	if (!data->temp_error1 ||
	    (data->min_efuse_value > data->temp_error1) ||
	    (data->temp_error1 > data->max_efuse_value))
		data->temp_error1 = data->efuse_value & EXYNOS_TMU_TEMP_MASK;
	WARN_ON_ONCE(data->cal_type == TYPE_TWO_POINT_TRIMMING);
}

static void exynos5433_sanitize_temp_error(struct exynos_tmu_data *data,
					   u32 trim_info)
{
	data->temp_error1 = trim_info & EXYNOS_TMU_TEMP_MASK;
	if (!data->temp_error1 ||
	    (data->min_efuse_value > data->temp_error1) ||
	    (data->temp_error1 > data->max_efuse_value))
		data->temp_error1 = data->efuse_value & EXYNOS_TMU_TEMP_MASK;

	if (data->cal_type == TYPE_TWO_POINT_TRIMMING) {
		data->temp_error2 = (trim_info >> EXYNOS_TRIMINFO_85_SHIFT) &
				    EXYNOS_TMU_TEMP_MASK;
		if (!data->temp_error2)
			data->temp_error2 = (data->efuse_value >>
					     EXYNOS_TRIMINFO_85_SHIFT) &
					    EXYNOS_TMU_TEMP_MASK;
	}
}

static void exynos7_sanitize_temp_error(struct exynos_tmu_data *data,
					u32 trim_info)
{
	data->temp_error1 = trim_info & EXYNOS7_TMU_TEMP_MASK;
	if (!data->temp_error1 ||
	    (data->min_efuse_value > data->temp_error1) ||
	    (data->temp_error1 > data->max_efuse_value))
		data->temp_error1 = data->efuse_value & EXYNOS7_TMU_TEMP_MASK;
	WARN_ON_ONCE(data->cal_type == TYPE_TWO_POINT_TRIMMING);
}

static void exynos850_sanitize_temp_error(struct exynos_tmu_data *data,
					   u32 trim_info)
{
	data->temp_error1 = trim_info & EXYNOS7_TMU_TEMP_MASK;
	if (!data->temp_error1 ||
	    (data->min_efuse_value > data->temp_error1) ||
	    (data->temp_error1 > data->max_efuse_value))
		data->temp_error1 = data->efuse_value & EXYNOS7_TMU_TEMP_MASK;

	if (data->cal_type == TYPE_TWO_POINT_TRIMMING) {
		data->temp_error2 = (trim_info >> EXYNOS7_TMU_TEMP_SHIFT) &
				    EXYNOS7_TMU_TEMP_MASK;
		if (!data->temp_error2)
			data->temp_error2 = (data->efuse_value >>
					     EXYNOS7_TMU_TEMP_SHIFT) &
					    EXYNOS_TMU_TEMP_MASK;
	}
}

Or maybe we could put tmu_temp_mask and tmu_85_shift in data instead,
and have one function like this:

static void sanitize_temp_error(struct exynos_tmu_data *data, u32 trim_info)
{
	data->temp_error1 = trim_info & data->tmu_temp_mask;
	if (!data->temp_error1 || (data->min_efuse_value > data->temp_error1) ||
	    (data->temp_error1 > data->max_efuse_value))
		data->temp_error1 = data->efuse_value & data->tmu_temp_mask;

	if (data->cal_type == TYPE_TWO_POINT_TRIMMING) {
		data->temp_error2 = (trim_info >> data->tmu_85_shift) &
				    data->tmu_temp_mask;
		if (!data->temp_error2)
			data->temp_error2 =
				(data->efuse_value >> data->tmu_85_shift) &
				data->tmu_temp_mask;
	}
}

Thank you,
