usb/xhci: fix compilation warning when !CONFIG_PCI && !CONFIG_PM
When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this warning: drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined but not used [-Wunused-function] Instead of creating nested #ifdefs, this patch fixes it by defining the xHCI PCI stubs as inline. This warning has been in since 3.2 kernel and was caused by commit 421aa841a134f6a743111cf44d0c6d3b45e3cf8c "usb/xhci: hide MSI code behind PCI bars", but wasn't noticed until 3.13 when a configuration with these options was tried Signed-off-by: David Cohen <david.a.cohen@linux.intel.com> Cc: stable@vger.kernel.org # 3.2 Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
