Subject: [PATCH 2/5] arm/pci: Use official API to iterate over PCI buses
Date: Fri, 15 May 2026 16:22:04 +0200 [thread overview]
Message-ID: <20260515-priv_root_buses-v1-2-f8e393c57390@linux.ibm.com> (raw)
In-Reply-To: <20260515-priv_root_buses-v1-0-f8e393c57390@linux.ibm.com>
Replace iterating over pci_root_buses with the official
pci_find_next_bus() call provided by PCI core. This allows to make
pci_root_buses private to PCI core.
