irq_dispose_mapping(pcie->irq) from the IRQ teardown\npath. pcie->irq is the parent IRQ returned by platform_get_irq(), not an\nIRQ created by the Altera INTx irq_domain, so the driver should detach\nthe chained handler but not dispose the parent IRQ mapping.\n\nPatch 2 fixes the original probe failure issue. The chained handler is\nnow installed only after the INTx domain is created, controller interrupts\nare disabled during teardown, and the IRQ setup is torn down if\npci_host_probe() fails.\n\nTested on Agilex 7 and Stratix 10:\n- Boot and fio read/write through a PCIe endpoint.\n- Probe-failure cleanup path by injecting a failure before\n pci_host_probe().\n\nChanges since v1:\n- Removed irq_dispose_mapping(pcie->irq), since pcie->irq is the parent\n IRQ returned by platform_get_irq().\n- Added controller interrupt disable helper.\n- Disabled controller interrupts before tearing down the chained handler\n and INTx domain.\n- Reused the teardown path when pci_host_probe() fails.\n\nv1:\nhttps://lore.kernel.org/linux-pci/20260427175302.570671-1-mahesh.vaidya@altera.com/\n\nMahesh Vaidya (2):\n PCI: altera: Do not dispose parent IRQ mapping\n PCI: altera: Fix resource leaks on probe failure\n\n drivers/pci/controller/pcie-altera.c | 36 +++++++++++++++++++++++++---\n 1 file changed, 33 insertions(+), 3 deletions(-)\n\n\nbase-commit: 4224e91fea5695a89843b4c38283016616946307" }
