Subject: [PATCH 0/2] PCI: of_property: Gracefully handle bridges without secondary bus
Date: Fri, 31 May 2024 13:18:58 +0200 [thread overview]
Message-ID: <cover.1717154083.git.namcao@linutronix.de> (raw)
Hi,
Some functions in of_property.c assume that bridges have subordinate bus.
This may not be true if we run out of bus number.
This series adds safety check in case bridges have no subordinate bus.
Nam Cao (2):
PCI: of_property: Fix NULL pointer defererence in
of_pci_prop_bus_range()
PCI: of_property: Fix NULL pointer defererence in
of_pci_prop_intr_map()
