Reviewed-by: Krzysztof Kozlowski Signed-off-by: Mateusz Majewski --- v3 -> v4: Resolved merge conflict and moved info about not outputting error to the correct commit message. v2 -> v3: Fixed error handling of devm_regulator_get_optional to handle the case in which the regulator is available, but enabling it fails. Also removed the error message, split into two commits and reworded the commit message. drivers/thermal/samsung/exynos_tmu.c | 49 +++++++++------------------- 1 file changed, 15 insertions(+), 34 deletions(-) diff --git a/drivers/thermal/samsung/exynos_tmu.c b/drivers/thermal/samsung/exynos_tmu.c index 8bcad8a70dc5..3bdcbab7466f 100644 --- a/drivers/thermal/samsung/exynos_tmu.c +++ b/drivers/thermal/samsung/exynos_tmu.c @@ -157,7 +157,6 @@ enum soc_type { * @reference_voltage: reference voltage of amplifier * in the positive-TC generator block * 0 < reference_voltage <= 31 - * @regulator: pointer to the TMU regulator structure. * @tzd: pointer to thermal_zone_device structure * @ntrip: number of supported trip points. * @enabled: current status of TMU device @@ -183,7 +182,6 @@ struct exynos_tmu_data { u16 temp_error1, temp_error2; u8 gain; u8 reference_voltage; - struct regulator *regulator; struct thermal_zone_device *tzd; unsigned int ntrip; bool enabled; @@ -994,50 +992,40 @@ static int exynos_tmu_probe(struct platform_device *pdev) * TODO: Add regulator as an SOC feature, so that regulator enable * is a compulsory call. */ - data->regulator = devm_regulator_get_optional(&pdev->dev, "vtmu"); - if (!IS_ERR(data->regulator)) { - ret = regulator_enable(data->regulator); - if (ret) { - dev_err(&pdev->dev, "failed to enable vtmu\n"); - return ret; - } - } else { - ret = PTR_ERR(data->regulator); - switch (ret) { - case -ENODEV: - break; - case -EPROBE_DEFER: - return -EPROBE_DEFER; - default: - dev_err(&pdev->dev, "Failed to get regulator: %d\n", - ret); - return ret; - } + ret = devm_regulator_get_enable_optional(&pdev->dev, "vtmu"); + switch (ret) { + case 0: + case -ENODEV: + break; + case -EPROBE_DEFER: + return -EPROBE_DEFER; + default: + dev_err(&pdev->dev, "Failed to get enabled regulator: %d\n", + ret); + return ret; } ret = exynos_map_dt_data(pdev); if (ret) - goto err_sensor; + return ret; data->clk = devm_clk_get(&pdev->dev, "tmu_apbif"); if (IS_ERR(data->clk)) { dev_err(&pdev->dev, "Failed to get clock\n"); - ret = PTR_ERR(data->clk); - goto err_sensor; + return PTR_ERR(data->clk); } data->clk_sec = devm_clk_get(&pdev->dev, "tmu_triminfo_apbif"); if (IS_ERR(data->clk_sec)) { if (data->soc == SOC_ARCH_EXYNOS5420_TRIMINFO) { dev_err(&pdev->dev, "Failed to get triminfo clock\n"); - ret = PTR_ERR(data->clk_sec); - goto err_sensor; + return PTR_ERR(data->clk_sec); } } else { ret = clk_prepare(data->clk_sec); if (ret) { dev_err(&pdev->dev, "Failed to get clock\n"); - goto err_sensor; + return ret; } } @@ -1107,10 +1095,6 @@ static int exynos_tmu_probe(struct platform_device *pdev) err_clk_sec: if (!IS_ERR(data->clk_sec)) clk_unprepare(data->clk_sec); -err_sensor: - if (!IS_ERR(data->regulator)) - regulator_disable(data->regulator); - return ret; } @@ -1124,9 +1108,6 @@ static void exynos_tmu_remove(struct platform_device *pdev) clk_unprepare(data->clk); if (!IS_ERR(data->clk_sec)) clk_unprepare(data->clk_sec); - - if (!IS_ERR(data->regulator)) - regulator_disable(data->regulator); } #ifdef CONFIG_PM_SLEEP
