hi Greg: > Why are you adding new functions but not actually calling them anywhere?
Below patch introduce a single helper, devm_platform_ioremap_resource, which combines platform_get_resource() and devm_ioremap_resource(). But there is no single helper to release those resources in driver removing stage. https://lore.kernel.org/lkml/20190215152507.31066-2-b...@bgdev.pl/ That means driver owner still need to call below (*) and (**) for releasing resource. Therefore, this patch adds a single release helper that can be paired with devm_platform_ioremap_resource. Appreciate ur kind help, foo_probe(pdev) { iomem = devm_platform_ioremap_resource(pdev, 0); .... } foo_remove(pdev) { devm_iounmap(iomem); (*) devm_release_mem_region(dev, res->start, size); (**) ........................ }
