Use local variable 'dev' instead of dereferencing it several times. Other relevant changes: Replace devm_add_action() with devm_add_action_or_reset()
This conversion was done automatically with coccinelle using the following semantic patches. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches - Replace devm_add_action() followed by failure action with devm_add_action_or_reset() - Drop unnecessary braces around conditional return statements - Use local variable 'struct device *dev' consistently Signed-off-by: Guenter Roeck <li...@roeck-us.net> --- drivers/input/misc/bfin_rotary.c | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) diff --git a/drivers/input/misc/bfin_rotary.c b/drivers/input/misc/bfin_rotary.c index a0fc18fdfc0c..9f5790c6e06b 100644 --- a/drivers/input/misc/bfin_rotary.c +++ b/drivers/input/misc/bfin_rotary.c @@ -141,25 +141,23 @@ static int bfin_rotary_probe(struct platform_device *pdev) /* Basic validation */ if ((pdata->rotary_up_key && !pdata->rotary_down_key) || - (!pdata->rotary_up_key && pdata->rotary_down_key)) { + (!pdata->rotary_up_key && pdata->rotary_down_key)) return -EINVAL; - } if (pdata->pin_list) { error = peripheral_request_list(pdata->pin_list, - dev_name(&pdev->dev)); + dev_name(dev)); if (error) { dev_err(dev, "requesting peripherals failed: %d\n", error); return error; } - error = devm_add_action(dev, bfin_rotary_free_action, - pdata->pin_list); + error = devm_add_action_or_reset(dev, bfin_rotary_free_action, + pdata->pin_list); if (error) { dev_err(dev, "setting cleanup action failed: %d\n", error); - peripheral_free_list(pdata->pin_list); return error; } } @@ -189,7 +187,7 @@ static int bfin_rotary_probe(struct platform_device *pdev) input->name = pdev->name; input->phys = "bfin-rotary/input0"; - input->dev.parent = &pdev->dev; + input->dev.parent = dev; input_set_drvdata(input, rotary); @@ -224,8 +222,8 @@ static int bfin_rotary_probe(struct platform_device *pdev) return -ENOENT; } - error = devm_request_irq(dev, rotary->irq, bfin_rotary_isr, - 0, dev_name(dev), rotary); + error = devm_request_irq(dev, rotary->irq, bfin_rotary_isr, 0, + dev_name(dev), rotary); if (error) { dev_err(dev, "unable to claim irq %d; error %d\n", rotary->irq, error); @@ -239,7 +237,7 @@ static int bfin_rotary_probe(struct platform_device *pdev) } platform_set_drvdata(pdev, rotary); - device_init_wakeup(&pdev->dev, 1); + device_init_wakeup(dev, 1); return 0; } -- 2.7.4
