From: Lee Jones Date: Tue, 7 Jul 2015 15:06:53 +0000 (+0100) Subject: regulator: pwm-regulator: Don't assign structure attributes right away X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5ad2cb14f5b8f3cb3d8688115037751b1ff45455;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git regulator: pwm-regulator: Don't assign structure attributes right away Perhaps this is just personal preference, but ... This patch introduces a new local variable to receive and test regulator initialisation data. It simplifies and cleans up the code making it that little bit easier to read and maintain. The local value is assigned to the structure attribute when all the others are. This is the way we usually do things. Prevents this kind of nonsense: this->is->just.silly = fetch_silly_value(&pointer); if (!this->is->just.silly) { printk("Silly value failed: %d\n", this->is->just.silly); return this->is->just.silly; } Signed-off-by: Lee Jones Signed-off-by: Mark Brown --- diff --git a/drivers/regulator/pwm-regulator.c b/drivers/regulator/pwm-regulator.c index d5cb267fa192..cb482089050b 100644 --- a/drivers/regulator/pwm-regulator.c +++ b/drivers/regulator/pwm-regulator.c @@ -218,6 +218,7 @@ static int pwm_regulator_init_continuous(struct platform_device *pdev, static int pwm_regulator_probe(struct platform_device *pdev) { + const struct regulator_init_data *init_data; struct pwm_regulator_data *drvdata; struct regulator_dev *regulator; struct regulator_config config = { }; @@ -240,14 +241,15 @@ static int pwm_regulator_probe(struct platform_device *pdev) if (ret) return ret; - config.init_data = of_get_regulator_init_data(&pdev->dev, np, - &pwm_regulator_desc); - if (!config.init_data) + init_data = of_get_regulator_init_data(&pdev->dev, np, + &pwm_regulator_desc); + if (!init_data) return -ENOMEM; config.of_node = np; config.dev = &pdev->dev; config.driver_data = drvdata; + config.init_data = init_data; drvdata->pwm = devm_pwm_get(&pdev->dev, NULL); if (IS_ERR(drvdata->pwm)) {
