From ff8e59bc4ec3f31789a47dce9b6fe44bd7bc5fcc Mon Sep 17 00:00:00 2001 From: Taku Izumi Date: Wed, 31 Oct 2012 09:51:48 +0900 Subject: [PATCH] PCI/portdrv: Don't create hotplug slots unless port supports hotplug Commit 2dcfaf85 mistakenly dropped the "flags & PCI_EXP_FLAGS_SLOT" test, so now we create hotplug slots even for PCIe port devices that don't support hotplug. This patch fixes this problem.
