requested IRQs, but it uses a loop variable\nthat is reused later in the function. When a later step fails, the\nunwind can run with an unexpected index value and leave some IRQs\nrequested.\n\nTrack the number of successfully requested IRQs separately and use that\ncounter for the unwind so all previously requested IRQs are freed on\nfailure.\n\nFixes: dc693d606644 (\"PCI: endpoint: pci-epf-vntb: Add MSI doorbell support\")\nSigned-off-by: Koichiro Den <den@valinux.co.jp>\n---\n drivers/pci/endpoint/functions/pci-epf-vntb.c | 11 ++++++-----\n 1 file changed, 6 insertions(+), 5 deletions(-)", "diff": "diff --git a/drivers/pci/endpoint/functions/pci-epf-vntb.c b/drivers/pci/endpoint/functions/pci-epf-vntb.c\nindex 20a400e83439..20efa27325f1 100644\n--- a/drivers/pci/endpoint/functions/pci-epf-vntb.c\n+++ b/drivers/pci/endpoint/functions/pci-epf-vntb.c\n@@ -523,6 +523,7 @@ static int epf_ntb_db_bar_init_msi_doorbell(struct epf_ntb *ntb,\n \t\t\t\t\t enum pci_barno barno)\n {\n \tstruct pci_epf *epf = ntb->epf;\n+\tunsigned int req;\n \tdma_addr_t low, high;\n \tstruct msi_msg *msg;\n \tsize_t sz;\n@@ -533,14 +534,14 @@ static int epf_ntb_db_bar_init_msi_doorbell(struct epf_ntb *ntb,\n \tif (ret)\n \t\treturn ret;\n \n-\tfor (i = 0; i < ntb->db_count; i++) {\n-\t\tret = request_irq(epf->db_msg[i].virq, epf_ntb_doorbell_handler,\n+\tfor (req = 0; req < ntb->db_count; req++) {\n+\t\tret = request_irq(epf->db_msg[req].virq, epf_ntb_doorbell_handler,\n \t\t\t\t 0, \"pci_epf_vntb_db\", ntb);\n \n \t\tif (ret) {\n \t\t\tdev_err(&epf->dev,\n \t\t\t\t\"Failed to request doorbell IRQ: %d\\n\",\n-\t\t\t\tepf->db_msg[i].virq);\n+\t\t\t\tepf->db_msg[req].virq);\n \t\t\tgoto err_free_irq;\n \t\t}\n \t}\n@@ -598,8 +599,8 @@ static int epf_ntb_db_bar_init_msi_doorbell(struct epf_ntb *ntb,\n \treturn 0;\n \n err_free_irq:\n-\tfor (i--; i >= 0; i--)\n-\t\tfree_irq(epf->db_msg[i].virq, ntb);\n+\twhile (req)\n+\t\tfree_irq(epf->db_msg[--req].virq, ntb);\n \n \tpci_epf_free_doorbell(ntb->epf);\n \treturn ret;\n", "prefixes": [ "1/4" ] }
