Re: [PATCH RESEND 16/20] virpci.c: use virPCIDeviceAddressPtr in virPCIDeviceListFindIndex()

We're going to need a way to remove a PCI Device from a list without having a valid virPCIDevicePtr, because the device is missing from the host. This means that virPCIDevicesListDel() must operate with a PCI Device address instead. Turns out that virPCIDevicesListDel() and its related functions only use the virPCIDeviceAddressPtr of the virPCIDevicePtr, so this change is simple to do and will not cause hassle in all other callers. Let's start adapting virPCIDeviceListFindIndex() and crawl our way up to virPCIDevicesListDel(). Signed-off-by: Daniel Henrique Barboza <danielhb413(a)gmail.com&gt;
