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/remoteproc/da8xx_remoteproc.c | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-) diff --git a/drivers/remoteproc/da8xx_remoteproc.c b/drivers/remoteproc/da8xx_remoteproc.c index 129f7b9..bb41ee0 100644 --- a/drivers/remoteproc/da8xx_remoteproc.c +++ b/drivers/remoteproc/da8xx_remoteproc.c @@ -201,23 +201,11 @@ static int da8xx_rproc_probe(struct platform_device *pdev) } bootreg_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); - if (!bootreg_res) { - dev_err(dev, - "platform_get_resource(IORESOURCE_MEM, 0): NULL\n"); - return -EADDRNOTAVAIL; - } - - chipsig_res = platform_get_resource(pdev, IORESOURCE_MEM, 1); - if (!chipsig_res) { - dev_err(dev, - "platform_get_resource(IORESOURCE_MEM, 1): NULL\n"); - return -EADDRNOTAVAIL; - } - bootreg = devm_ioremap_resource(dev, bootreg_res); if (IS_ERR(bootreg)) return PTR_ERR(bootreg); + chipsig_res = platform_get_resource(pdev, IORESOURCE_MEM, 1); chipsig = devm_ioremap_resource(dev, chipsig_res); if (IS_ERR(chipsig)) return PTR_ERR(chipsig); -- 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
