[PATCH 5/5] usb/xhci: fix compilation warning when !CONFIG_PCI && !CONFIG_PM

From: Mathias Nyman
Date: Tue Apr 22 2014 - 08:12:56 EST


From: David Cohen <david.a.cohen@xxxxxxxxxxxxxxx>

When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this
warning:
drivers/usb/host/xhci.c:409:13: warning: âxhci_msix_sync_irqsâ defined
but not used [-Wunused-function]

Instead of creating nested #ifdefs, this patch fixes it by defining the
xHCI PCI stubs as inline.
