From cde4986cec6f6bb379ce08c5d55057ea768906db Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Sat, 21 Jul 2012 10:54:47 +1000 Subject: [PATCH] drivers/video/backlight/ot200_bl.c: use devm_ functions The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc of these functions Signed-off-by: Jingoo Han Cc: Christian Gmeiner Cc: Richard Purdie Signed-off-by: Andrew Morton --- drivers/video/backlight/ot200_bl.c | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) diff --git a/drivers/video/backlight/ot200_bl.c b/drivers/video/backlight/ot200_bl.c index f519d55a294c..ef637ffc0799 100644 --- a/drivers/video/backlight/ot200_bl.c +++ b/drivers/video/backlight/ot200_bl.c @@ -97,10 +97,10 @@ static int ot200_backlight_probe(struct platform_device *pdev) goto error_mfgpt_alloc; } - data = kzalloc(sizeof(*data), GFP_KERNEL); + data = devm_kzalloc(&pdev->dev, sizeof(*data), GFP_KERNEL); if (!data) { retval = -ENOMEM; - goto error_kzalloc; + goto error_devm_kzalloc; } /* setup gpio */ @@ -122,16 +122,14 @@ static int ot200_backlight_probe(struct platform_device *pdev) if (IS_ERR(bl)) { dev_err(&pdev->dev, "failed to register backlight\n"); retval = PTR_ERR(bl); - goto error_backlight_device_register; + goto error_devm_kzalloc; } platform_set_drvdata(pdev, bl); return 0; -error_backlight_device_register: - kfree(data); -error_kzalloc: +error_devm_kzalloc: cs5535_mfgpt_free_timer(pwm_timer); error_mfgpt_alloc: gpio_free(GPIO_DIMM); @@ -141,7 +139,6 @@ error_mfgpt_alloc: static int ot200_backlight_remove(struct platform_device *pdev) { struct backlight_device *bl = platform_get_drvdata(pdev); - struct ot200_backlight_data *data = bl_get_data(bl); backlight_device_unregister(bl); @@ -154,7 +151,6 @@ static int ot200_backlight_remove(struct platform_device *pdev) cs5535_mfgpt_free_timer(pwm_timer); gpio_free(GPIO_DIMM); - kfree(data); return 0; } -- 2.39.5
