If anyone has any objections, please let me know. ------------------ From: Joerg Roedel 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.] Signed-off-by: Joerg Roedel Signed-off-by: Rafael J.
