| Subject: ACPI: AMBA: Fix resource name in /proc/iomem |
| |
| From: Liguang Zhang <zhangliguang@linux.alibaba.com> |
| |
| [ 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. |
