| |
3.16.46-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Joerg Roedel <jroedel@suse.de>
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.]
