This can lead to some static analysis tools such as the\ncompiler sanitizers complaining about double free problems.\n\nSince ice_init_interrupt_scheme already unrolls internally on failure,\nthere is no need to call ice_clear_interrupt_scheme when it fails. Add\na new unroll label and use that instead.\n\nSigned-off-by: Jacob Keller <jacob.e.keller@intel.com>\n---\n drivers/net/ethernet/intel/ice/ice_main.c | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ice/ice_main.c b/drivers/net/ethernet/intel/ice/ice_main.c\nindex 1853dca3f364..943fde5abdb7 100644\n--- a/drivers/net/ethernet/intel/ice/ice_main.c\n+++ b/drivers/net/ethernet/intel/ice/ice_main.c\n@@ -3443,7 +3443,7 @@ ice_probe(struct pci_dev *pdev, const struct pci_device_id __always_unused *ent)\n \tif (err) {\n \t\tdev_err(dev, \"ice_init_interrupt_scheme failed: %d\\n\", err);\n \t\terr = -EIO;\n-\t\tgoto err_init_interrupt_unroll;\n+\t\tgoto err_init_vsi_unroll;\n \t}\n \n \t/* In case of MSIX we are going to setup the misc vector right here\n@@ -3564,6 +3564,7 @@ ice_probe(struct pci_dev *pdev, const struct pci_device_id __always_unused *ent)\n \tice_free_irq_msix_misc(pf);\n err_init_interrupt_unroll:\n \tice_clear_interrupt_scheme(pf);\n+err_init_vsi_unroll:\n \tdevm_kfree(dev, pf->vsi);\n err_init_pf_unroll:\n \tice_deinit_pf(pf);\n", "prefixes": [ "S44", "12/14" ] }
