Hi Joerg, After merging the iommu tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
In file included from drivers/pci/pci.c:32:
include/linux/pci-ats.h:70:12: warning: 'pci_prg_resp_pasid_required' defined
but not used [-Wunused-function]
static int pci_prg_resp_pasid_required(struct pci_dev *pdev)
^~~~~~~~~~~~~~~~~~~~~~~~~~~
Introduced by commit
e5567f5f6762 ("PCI/ATS: Add pci_prg_resp_pasid_required() interface.")
The non CONFIG_PCI_PASID version needs an "inline".
