Subject: ACPI: Do not create a platform_device for IOAPIC/IOxAPIC
From: Joerg Roedel <jroedel@xxxxxxx>
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.]
