Subject: [PATCH-for-10.0 v2 07/13] hw/pci: Propagate bar_at_addr_0_refused to pci_root_bus_new()
Date: Tue, 26 Nov 2024 12:22:06 +0100	[thread overview]
Message-ID: <20241126112212.64524-8-philmd@linaro.org> (raw)
In-Reply-To: <20241126112212.64524-1-philmd@linaro.org>

Have pci_root_bus_new() callers set the
'bar_at_addr_0_refused' argument. No logical change.
