| Subject: [PATCH] ACPI: Do not create a platform_device for IOAPIC/IOxAPIC |
| |
| commit 08f63d97749185fab942a3a47ed80f5bd89b8b7d upstream. |
| |
| No platform-device is required for IO(x)APICs, so don't even |
| create them. |
| |
| [ rjw: This fixes a problem with leaking platform device objects |
| after IOAPIC/IOxAPIC hot-removal events.] |
