[libvirt] [PATCH v2 07/15] qemu: Clear out qemuDomainDeviceDefValidateControllerPCI()

We will rewrite pretty much every single line of this function over the course of the next several commits, and starting from a clean slate rather than replacing it bit by bit makes the resulting diffs unmeasurably easier to read and understand, and you need fewer of them to boot. Trust me, I tried the other approach first :) Signed-off-by: Andrea Bolognani <abologna(a)redhat.com&gt; --- src/qemu/qemu_domain.c | 199 +------------------------------------------------ 1 file changed, 2 insertions(+), 197 deletions(-) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 2fbae695a..9dc3d5597 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -4243,204 +4243,9 @@ qemuDomainDeviceDefValidateControllerSCSI(const virDomainControllerDef *controll static int -qemuDomainDeviceDefValidateControllerPCI(const virDomainControllerDef *controller, - const virDomainDef *def) +qemuDomainDeviceDefValidateControllerPCI(const virDomainControllerDef *controller ATTRIBUTE_UNUSED, + const virDomainDef *def ATTRIBUTE_UNUSED) { - virDomainControllerModelPCI model = controller->model;
