ACPI: AMBA: Fix resource name in /proc/iomem
[ Upstream commit 7718629432676b5ebd9a32940782fe297a0abf8d ]
In function amba_handler_attach(), dev->res.name is initialized by
amba_device_alloc. But when address_found is false, dev->res.name is
assigned to null value, which leads to wrong resource name display in
/proc/iomem, "<BAD>" is seen for those resources.
