I think this got broken by the move to drivers/pci/controllers, so I added this: Fixes: 6e0832fa432e ("PCI: Collect all native drivers under drivers/pci/controller/") > --- > drivers/pci/Makefile | 6 +++--- > 1 files changed, 3 insertions(+), 3 deletions(-) > > diff --git a/drivers/pci/Makefile b/drivers/pci/Makefile > index 5352019..1b2cfe5 100644 > --- a/drivers/pci/Makefile > +++ b/drivers/pci/Makefile > @@ -28,10 +28,10 @@ obj-$(CONFIG_PCI_PF_STUB) += pci-pf-stub.o > obj-$(CONFIG_PCI_ECAM) += ecam.o > obj-$(CONFIG_XEN_PCIDEV_FRONTEND) += xen-pcifront.o > > -obj-y += controller/ > -obj-y += switch/ > - > # Endpoint library must be initialized before its users > obj-$(CONFIG_PCI_ENDPOINT) += endpoint/ > > +obj-y += controller/ > +obj-y += switch/ > + > ccflags-$(CONFIG_PCI_DEBUG) := -DDEBUG > -- > 1.7.1 >

The Endpoint library must be initialized before its users, which are in drivers/pci/controllers This change corrects a kernel crash when loading the Cadence EP driver, since it calls devm_pci_epc_create() and this is only valid once the Endpoint library has been initialized.
