Subject: [PATCH] USB: don't build PCI quirks if USB support isn't configured
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The USB PCI quirks code gets built into the kernel whenever CONFIG_PCI
is enabled, even if CONFIG_USB is not set.  This can cause unnecessary
messages to show up in the kernel log, such as "CONFIG_USB_XHCI_HCD is
turned off, defaulting to EHCI" (which makes no sense when the kernel
has been configured without host-side USB support).

This patch addresses the problem by building pci-quirks.o only when
CONFIG_PCI and CONFIG_USB are both enabled.
