From: Julia Lawall <Julia.Lawall@xxxxxxx> Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/input/keyboard/imx_keypad.c | 7 +------ drivers/input/keyboard/nspire-keypad.c | 7 +------ drivers/input/keyboard/spear-keyboard.c | 7 +------ drivers/input/serio/arc_ps2.c | 7 +------ drivers/input/serio/olpc_apsp.c | 3 --- 5 files changed, 4 insertions(+), 27 deletions(-) diff --git a/drivers/input/keyboard/imx_keypad.c b/drivers/input/keyboard/imx_keypad.c index 03c8cc5..328cfc1 100644 --- a/drivers/input/keyboard/imx_keypad.c +++ b/drivers/input/keyboard/imx_keypad.c @@ -442,12 +442,6 @@ static int imx_keypad_probe(struct platform_device *pdev) return -EINVAL; } - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (res == NULL) { - dev_err(&pdev->dev, "no I/O memory defined in platform data\n"); - return -EINVAL; - } - input_dev = devm_input_allocate_device(&pdev->dev); if (!input_dev) { dev_err(&pdev->dev, "failed to allocate the input device\n"); @@ -468,6 +462,7 @@ static int imx_keypad_probe(struct platform_device *pdev) setup_timer(&keypad->check_matrix_timer, imx_keypad_check_for_events, (unsigned long) keypad); + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); keypad->mmio_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(keypad->mmio_base)) return PTR_ERR(keypad->mmio_base); diff --git a/drivers/input/keyboard/nspire-keypad.c b/drivers/input/keyboard/nspire-keypad.c index 20d872d..b3e3eda 100644 --- a/drivers/input/keyboard/nspire-keypad.c +++ b/drivers/input/keyboard/nspire-keypad.c @@ -171,12 +171,6 @@ static int nspire_keypad_probe(struct platform_device *pdev) return -EINVAL; } - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "missing platform resources\n"); - return -EINVAL; - } - keypad = devm_kzalloc(&pdev->dev, sizeof(struct nspire_keypad), GFP_KERNEL); if (!keypad) { @@ -208,6 +202,7 @@ static int nspire_keypad_probe(struct platform_device *pdev) return PTR_ERR(keypad->clk); } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); keypad->reg_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(keypad->reg_base)) return PTR_ERR(keypad->reg_base); diff --git a/drivers/input/keyboard/spear-keyboard.c b/drivers/input/keyboard/spear-keyboard.c index 7111124..85ff530 100644 --- a/drivers/input/keyboard/spear-keyboard.c +++ b/drivers/input/keyboard/spear-keyboard.c @@ -191,12 +191,6 @@ static int spear_kbd_probe(struct platform_device *pdev) int irq; int error; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "no keyboard resource defined\n"); - return -EBUSY; - } - irq = platform_get_irq(pdev, 0); if (irq < 0) { dev_err(&pdev->dev, "not able to get irq for the device\n"); @@ -228,6 +222,7 @@ static int spear_kbd_probe(struct platform_device *pdev) kbd->suspended_rate = pdata->suspended_rate; } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); kbd->io_base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(kbd->io_base)) return PTR_ERR(kbd->io_base); diff --git a/drivers/input/serio/arc_ps2.c b/drivers/input/serio/arc_ps2.c index 3fb7727..8024a6d 100644 --- a/drivers/input/serio/arc_ps2.c +++ b/drivers/input/serio/arc_ps2.c @@ -189,12 +189,6 @@ static int arc_ps2_probe(struct platform_device *pdev) int irq; int error, id, i; - res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) { - dev_err(&pdev->dev, "no IO memory defined\n"); - return -EINVAL; - } - irq = platform_get_irq_byname(pdev, "arc_ps2_irq"); if (irq < 0) { dev_err(&pdev->dev, "no IRQ defined\n"); @@ -208,6 +202,7 @@ static int arc_ps2_probe(struct platform_device *pdev) return -ENOMEM; } + res = platform_get_resource(pdev, IORESOURCE_MEM, 0); arc_ps2->addr = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(arc_ps2->addr)) return PTR_ERR(arc_ps2->addr); diff --git a/drivers/input/serio/olpc_apsp.c b/drivers/input/serio/olpc_apsp.c index 818aa46..51b1d40 100644 --- a/drivers/input/serio/olpc_apsp.c +++ b/drivers/input/serio/olpc_apsp.c @@ -183,9 +183,6 @@ static int olpc_apsp_probe(struct platform_device *pdev) np = pdev->dev.of_node; res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!res) - return -ENOENT; - priv->base = devm_ioremap_resource(&pdev->dev, res); if (IS_ERR(priv->base)) { dev_err(&pdev->dev, "Failed to map WTM registers\n"); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
