Subject: [PATCH] Input: tegra-kbc - use devm_platform_ioremap_resource

---

devm_platform_get_and_ioremap_resource maps a resource and returns its
physical address. If we don't need the physical address, we should call
devm_platform_ioremap_resource instead.

But the patch also isn't wrong, so while I'm at it:
