[PATCH v9 14/17] hw/pci-bridge/pcie_pci_bridge: Omit errp for pci_add_capability |
Date: |

Omitting errp for pci_add_capability() causes it to abort if
capabilities overlap. This behavior is appropriate heare because all of
the capabilities set in this device are defined in the program and
their overlap should not happen unless there is a programming error.
