[Qemu-devel] [PULL 5/5] usb: move ehci_create_ich9_with_companions to hw/i386

[Gerd Hoffmann <kraxel@redhat.com>]

From: Paolo Bonzini <pbonzini@redhat.com>

This function is only needed when Q35 is in use.  Moving it to
the same file that uses it lets you disable the entire USB
subsystem in x86_64-softmmu.mak; of course doing that will
cause -usb to break horribly, but one thing at a time.
