gpio: timberdale: Switch to devm_ioremap_resource()
Replace calls to devm_request_mem_region and devm_ioremap with a direct call to devm_ioremap_resource instead and modify error handling. 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 Coccinelle semantic patch that is used to make this change is as follows: //<smpl> @nm@ expression myname; identifier i; @@ struct platform_driver i = { .driver = { .name = myname } }; @@ expression dev,res,size,e1,e; expression nm.myname; @@ -if (!devm_request_mem_region(dev, res->start, size, - \(res->name\|dev_name(dev)\|myname\))) { - ... - return ...; -} ... when != res->start = e1 e = -devm_ioremap(dev,res->start,size); +devm_ioremap_resource(dev,res); if -(e == NULL) +(IS_ERR(e)) { ... -return ...; +return PTR_ERR(e); } //</smpl> Further, updated error handling by hand as devm_ioremap_resource gives appropriate error messages, so remove unnecessary error messages.
