This was\nmodified to handle the specific case of -ENXIO separately, allowing the\nfunction to proceed without logging the error in this case. However,\nthis change unintentionally left a path where md_autodetect_dev()\ncould be called without confirming that part is a valid pointer.\n\nThis commit separates the error handling logic by splitting the\ninitial if-condition, improving code readability and handling specific\nerror scenarios explicitly. The function now distinguishes the general\nerror case from -ENXIO without altering the existing behavior of\nmd_autodetect_dev() calls.","state":0,"publishedAt":"2024-10-21T11:53:40.071+00:00","modifiedAt":"2026-10-15T00:51:59.574+00:00","affected":[{"ecosystem":"Vendor
