This does no harm unless one of the functions\nrequesting the IRQ fails and attempt to free the IRQ.\n\nThis may end up with a warning from the IRQ core that is expecting the\naffinity hint to be cleared before freeing the IRQ:\n\nkernel/irq/manage.c:\n\n\t/* make sure affinity_hint is cleaned up */\n\tif (WARN_ON_ONCE(desc->affinity_hint))\n\t\tdesc->affinity_hint = NULL;\n\nSo to fix this issue, clear the IRQ affinity hint before calling\nath12k_pci_free_irq() in the error path. The affinity will be cleared once\nagain further down the error path due to code organization, but that does\nno harm.\n\n## Affected\n\n- `Linux >= a3012f206d07fa62b5c2e384cbc3a81a4dbba3c9 < a69a594794fcad96d4cfce12aab6c5014a12b4c8`\n- `Linux >= a3012f206d07fa62b5c2e384cbc3a81a4dbba3c9 < 35b33ba76765ce9e72949d957f3cf1feafd2955c`\n- `Linux >= a3012f206d07fa62b5c2e384cbc3a81a4dbba3c9 < b43b1e2c52db77c872bd60d30cdcc72c47df70c7`\n- `Linux 6.8`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
