But there is one more which  \napplies here.  \n  \nIf the DSA master itself is on a bus that calls ->remove from ->shutdown  \n(like dpaa2-eth, which is on the fsl-mc bus), there is a device link  \nbetween the switch and the DSA master, and device_links_unbind_consumers()  \nwill unbind the bcm_sf2 switch driver on shutdown.  \n  \nSo the same treatment must be applied to all DSA switch drivers, which  \nis: either use devres for both the mdiobus allocation and registration,  \nor don't use devres at all.  \n  \nThe bcm_sf2 driver has the code structure in place for orderly mdiobus  \nremoval, so just replace devm_mdiobus_alloc() with the non-devres  \nvariant, and add manual free where necessary, to ensure that we don't  \nlet devres free a still-registered bus. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"16 Jul 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-07-16T15:26:29.000000Z"}]}
